1 Samuel 17:31-52 31 And when the words were heard which David spake, they rehearsed them before Saul; and he sent for him. 32 And David said to Saul, Let no man's heart fail because of him; thy servant will go and fight with this Philistine. 33 And Saul said to David, Thou art not able to go against this Philistine to fight with him; for thou art but a youth, and he a man of war from his youth. 34 And David said unto Saul, Thy servant was keeping his father's sheep; and when there came a lion, or a bear, and took a lamb out of the flock, 35 I went out after him, and smote him, and delivered it out of his mouth; and when he arose against me, I caught him by his beard, and smote him, and slew him. 36 Thy servant smote both the lion and the bear: and this uncircumcised Philistine shall be as one of them, seeing he hath defied the armies of the living God. 37 And David said, Jehovah that delivered me out of the paw of the lion, and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and Jehovah shall be with thee. 38 And Saul clad David with his apparel, and he put a helmet of brass upon his head, and he clad him with a coat of mail. 39 And David girded his sword upon his apparel, and he assayed to go; for he had not proved it. And David said unto Saul, I cannot go with these; for I have not proved them. And David put them off him. 40 And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag which he had, even in his wallet; and his sling was in his hand: and he drew near to the Philistine. 41 And the Philistine came on and drew near unto David; and the man that bare the shield went before him. 42 And when the Philistine looked about, and saw David, he disdained him; for he was but a youth, and ruddy, and withal of a fair countenance. 43 And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods. 44 And the Philistine said to David, Come to me, and I will give thy flesh unto the birds of the heavens, and to the beasts of the field. 45 Then said David to the Philistine, Thou comest to me with a sword, and with a spear, and with a javelin: but I come to thee in the name of Jehovah of hosts, the God of the armies of Israel, whom thou hast defied. 46 This day will Jehovah deliver thee into my hand; and I will smite thee, and take thy head from off thee; and I will give the dead bodies of the host of the Philistines this day unto the birds of the heavens, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel, 47 and that all this assembly may know that Jehovah saveth not with sword and spear: for the battle is Jehovah's, and he will give you into our hand. 48 And it came to pass, when the Philistine arose, and came and drew nigh to meet David, that David hastened, and ran toward the army to meet the Philistine. 49 And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead; and the stone sank into his forehead, and he fell upon his face to the earth. 50 So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David. 51 Then David ran, and stood over the Philistine, and took his sword, and drew it out of the sheath thereof, and slew him, and cut off his head therewith. And when the Philistines saw that their champion was dead, they fled. 52 And the men of Israel and of Judah arose, and shouted, and pursued the Philistines, until thou comest to Gai, and to the gates of Ekron. And the wounded of the Philistines fell down by the way to Shaaraim, even unto Gath, and unto Ekron.

The well-known story of David and Goliath teaches believers that obstacles in our life are no match for God. Whether our Goliath is a relational challenge or an overwhelming situation, we must realize that the Lord is sovereign over everything in heaven and on earth, and He has the power to give us the victory. 

David had unshakeable trust because past experience had proven that God was faithful. The young shepherd recalled how the Lord gave him the victory on two separate occasions, when a lion and a bear threatened his flock (1 Sam. 17:37).

Our faith is bolstered in a similar way by remembering God’s provision in our own life and by reading about His faithfulness to men and women in the Bible. This is why it’s helpful to keep a record of God’s faithfulness. Then when facing a trial, we can look back at what we’ve journaled and be strengthened, knowing that God has proven trustworthy in the past.

Trusting in the Lord gives us the courage to face our giants. Being so armed, we can respond to challenges on the basis of three important truths:

• Who Christ is in us—our Savior and Provider.
• Who we are in Christ—God’s adopted children, eternally secure and indwelt by the Holy Spirit.
• What we have in Christ—the promise of access to almighty God.

Instead of fixing our attention on how big the obstacle is, let’s begin focusing on the greatness of our God. If we’ll trust and obey Him, His Spirit will equip us for the challenge, and our faith will glorify Him.

Bible in One Year: 1 Chronicles 19-21 Chapter 19 1 And it came to pass after this, that Nahash the king of the children of Ammon died, and his son reigned in his stead. 2 And David said, I will show kindness unto Hanun the son of Nahash, because his father showed kindness to me. So David sent messengers to comfort him concerning his father. And David's servants came into the land of the children of Ammon to Hanun, to comfort him. 3 But the princes of the children of Ammon said to Hanun, Thinkest thou that David doth honor thy father, in that he hath sent comforters unto thee? are not his servants come unto thee to search, and to overthrow, and to spy out the land? 4 So Hanun took David's servants, and shaved them, and cut off their garments in the middle, even to their buttocks, and sent them away. 5 Then there went certain persons, and told David how the men were served. And he sent to meet them; for the men were greatly ashamed. And the king said, Tarry at Jericho until your beards be grown, and then return. 6 And when the children of Ammon saw that they had made themselves odious to David, Hanun and the children of Ammon sent a thousand talents of silver to hire them chariots and horsemen out of Mesopotamia, and out of Arammaacah, and out of Zobah. 7 So they hired them thirty and two thousand chariots, and the king of Maacah and his people, who came and encamped before Medeba. And the children of Ammon gathered themselves together from their cities, and came to battle. 8 And when David heard of it, he sent Joab, and all the host of the mighty men. 9 And the children of Ammon came out, and put the battle in array at the gate of the city: and the kings that were come were by themselves in the field. 10 Now when Joab saw that the battle was set against him before and behind, he chose of all the choice men of Israel, and put them in array against the Syrians. 11 And the rest of the people he committed into the hand of Abishai his brother; and they put themselves in array against the children of Ammon. 12 And he said, If the Syrians be too strong for me, then thou shalt help me; but if the children of Ammon be too strong for thee, then I will help thee. 13 Be of good courage, and let us play the man for our people, and for the cities of our God: and Jehovah do that which seemeth him good. 14 So Joab and the people that were with him drew nigh before the Syrians unto the battle; and they fled before him. 15 And when the children of Ammon saw that the Syrians were fled, they likewise fled before Abishai his brother, and entered into the city. Then Joab came to Jerusalem. 16 And when the Syrians saw that they were put to the worse before Israel, they sent messengers, and drew forth the Syrians that were beyond the River, with Shophach the captain of the host of Hadarezer at their head. 17 And it was told David; and he gathered all Israel together, and passed over the Jordan, and came upon them, and set the battle in array against them. So when David had put the battle in array against the Syrians, they fought with him. 18 And the Syrians fled before Israel; and David slew of the Syrians `the men of' seven thousand chariots, and forty thousand footmen, and killed Shophach the captain of the host. 19 And when the servants of Hadarezer saw that they were put to the worse before Israel, they made peace with David, and served him: neither would the Syrians help the children of Ammon any more. Chapter 20 1 And it came to pass, at the time of the return of the year, at the time when kings go out `to battle', that Joab led forth the army, and wasted the country of the children of Ammon, and came and besieged Rabbah. But David tarried at Jerusalem. And Joab smote Rabbah, and overthrew it. 2 And David took the crown of their king from off his head, and found it to weigh a talent of gold, and there were precious stones in it; and it was set upon David's head: and he brought forth the spoil of the city, exceeding much. 3 And he brought forth the people that were therein, and cut `them' with saws, and with harrows of iron, and with axes. And thus did David unto all the cities of the children of Ammon. And David and all the people returned to Jerusalem. 4 And it came to pass after this, that there arose war at Gezer with the Philistines: then Sibbecai the Hushathite slew Sippai, of the sons of the giant; and they were subdued. 5 And there was again war with the Philistines; and Elhanan the son of Jair slew Lahmi the brother of Goliath the Gittite, the staff of whose spear was like a weaver's beam. 6 And there was again war at Gath, where was a man of great stature, whose fingers and toes were four and twenty, six `on each hand', and six `on each foot'; and he also was born unto the giant. 7 And when he defied Israel, Jonathan the son of Shimea David's brother slew him. 8 These were born unto the giant in Gath; and they fell by the hand of David, and by the hand of his servants. Chapter 21 1 And Satan stood up against Israel, and moved David to number Israel. 2 And David said to Joab and to the princes of the people, Go, number Israel from Beer-sheba even to Dan; and bring me word, that I may know the sum of them. 3 And Joab said, Jehovah make his people a hundred times as many as they are: but, my lord the king, are they not all my lord's servants? why doth my lord require this thing? why will he be a cause of guilt unto Israel? 4 Nevertheless the king's word prevailed against Joab. Wherefore Joab departed, and went throughout all Israel, and came to Jerusalem. 5 And Joab gave up the sum of the numbering of the people unto David. And all they of Israel were a thousand thousand and a hundred thousand men that drew sword: and Judah was four hundred threescore and ten thousand men that drew sword. 6 But Levi and Benjamin counted he not among them; for the king's word was abominable to Joab. 7 And God was displeased with this thing; therefore he smote Israel. 8 And David said unto God, I have sinned greatly, in that I have done this thing: but now, put away, I beseech thee, the iniquity of thy servant; for I have done very foolishly. 9 And Jehovah spake unto Gad, David's seer, saying, 10 Go and speak unto David, saying, Thus saith Jehovah, I offer thee three things: choose thee one of them, that I may do it unto thee. 11 So Gad came to David, and said unto him, Thus saith Jehovah, Take which thou wilt: 12 either three years of famine; or three months to be consumed before thy foes, while the sword of thine enemies overtaketh thee; or else three days the sword of Jehovah, even pestilence in the land, and the angel of Jehovah destroying throughout all the borders of Israel. Now therefore consider what answer I shall return to him that sent me. 13 And David said unto Gad, I am in a great strait: let me fall, I pray, into the hand of Jehovah; for very great are his mercies: and let me not fall into the hand of man. 14 So Jehovah sent a pestilence upon Israel; and there fell of Israel seventy thousand men. 15 And God sent an angel unto Jerusalem to destroy it: and as he was about to destroy, Jehovah beheld, and he repented him of the evil, and said to the destroying angel, It is enough; now stay thy hand. And the angel of Jehovah was standing by the threshing-floor of Ornan the Jebusite. 16 And David lifted up his eyes, and saw the angel of Jehovah standing between earth and heaven, having a drawn sword in his hand stretched out over Jerusalem. Then David and the elders, clothed in sackcloth, fell upon their faces. 17 And David said unto God, Is it not I that commanded the people to be numbered? even I it is that have sinned and done very wickedly; but these sheep, what have they done? let thy hand, I pray thee, O Jehovah my God, be against me, and against my father's house; but not against thy people, that they should be plagued. 18 Then the angel of Jehovah commanded Gad to say to David, that David should go up, and rear an altar unto Jehovah in the threshing-floor of Ornan the Jebusite. 19 And David went up at the saying of Gad, which he spake in the name of Jehovah. 20 And Ornan turned back, and saw the angel; and his four sons that were with him hid themselves. Now Ornan was threshing wheat. 21 And as David came to Ornan, Ornan looked and saw David, and went out of the threshing-floor, and bowed himself to David with his face to the ground. 22 Then David said to Ornan, Give me the place of this threshing-floor, that I may build thereon an altar unto Jehovah: for the full price shalt thou give it me, that the plague may be stayed from the people. 23 And Ornan said unto David, Take it to thee, and let my lord the king do that which is good in his eyes: lo, I give `thee' the oxen for burnt-offerings, and the threshing instruments for wood, and the wheat for the meal-offering; I give it all. 24 And king David said to Ornan, Nay; but I will verily buy it for the full price: for I will not take that which is thine for Jehovah, nor offer a burnt-offering without cost. 25 So David gave to Ornan for the place six hundred shekels of gold by weight. 26 And David built there an altar unto Jehovah, and offered burnt-offerings and peace-offerings, and called upon Jehovah; and he answered him from heaven by fire upon the altar of burnt-offering. 27 And Jehovah commanded the angel; and he put up his sword again into the sheath thereof. 28 At that time, when David saw that Jehovah had answered him in the threshing-floor of Ornan the Jebusite, then he sacrificed there. 29 For the tabernacle of Jehovah, which Moses made in the wilderness, and the altar of burnt-offering, were at that time in the high place at Gibeon. 30 But David could not go before it to inquire of God; for he was afraid because of the sword of the angel of Jehovah.
