Guarding Against Sin

A devotional by Grace To You for reading on January 4th

“I, therefore, the prisoner of the Lord, entreat you to walk in a manner worthy of the calling with which you have been called” ( Ephesians 4:1 Chapter 4 1 I therefore, the prisoner in the Lord, beseech you to walk worthily of the calling wherewith ye were called, ).

Knowing and obeying God’s Word helps us walk worthy by protecting us from sin.

While we are discussing the importance of knowing right doctrine before right duty, let’s see one way knowing the Bible helps us to walk worthy: it protects us from sin. From time to time you might hear people who have a fatalistic attitude toward sin saying, “I couldn’t help myself” or “The Devil made me do it.” Such excuses are foolish for Christians to make since God has given us the means to resist temptation.

The psalmist said, “Thy word I have treasured in my heart, that I may not sin against Thee” (Ps. 119:11). Without knowledge, we are defenseless and vulnerable. Knowing God’s truth—by study and by application—enables us to say no to sin and yes to righteousness. Anyone who puts his faith in Jesus Christ but who does not keep God’s Word constantly at the forefront of his mind will find himself entrapped in sin again and again.

Although we must know God’s Word to defend ourselves against sin and to obey God’s will, there is a danger. Once we know His truth, we are held accountable for what we know.

Second Peter 2:21 speaks of apostates, those who knew about Jesus Christ but returned to their former life without ever committing themselves to Him: “It would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment delivered to them.” James 4:17 17 To him therefore that knoweth to do good, and doeth it not, to him it is sin. says, “To one who knows the right thing to do, and does not do it, to him it is sin.”

So not knowing is better than knowing and not obeying. What’s best, of course, is knowing the Word and obeying it, because it is our spiritual nourishment: “Like newborn babes, long for the pure milk of the word, that by it you may grow in respect to salvation” ( 1 Peter 2:2 2 as newborn babes, long for the spiritual milk which is without guile, that ye may grow thereby unto salvation; ). For a Christian, neglecting the Word is spiritual starvation.

Suggestions for Prayer

Ask forgiveness for times you have known the right thing to do but have not done it.

For Further Study

  • Read about a young man who gave in to temptation in Proverbs 7 Chapter 7 1 My son, keep my words, And lay up my commandments with thee. 2 Keep my commandments and live; And my law as the apple of thine eye. 3 Bind them upon thy fingers; Write them upon the tablet of thy heart. 4 Say unto wisdom, Thou art my sister; And call understanding `thy' kinswoman: 5 That they may keep thee from the strange woman, From the foreigner that flattereth with her words. 6 For at the window of my house I looked forth through my lattice; 7 And I beheld among the simple ones, I discerned among the youths, A young man void of understanding, 8 Passing through the street near her corner; And he went the way to her house, 9 In the twilight, in the evening of the day, In the middle of the night and in the darkness. 10 And, behold, there met him a woman With the attire of a harlot, and wily of heart. 11 She is clamorous and wilful; Her feet abide not in her house: 12 Now she is in the streets, now in the broad places, And lieth in wait at every corner. 13 So she caught him, and kissed him, `And' with an impudent face she said unto him: 14 Sacrifices of peace-offerings are with me; This day have I paid my vows. 15 Therefore came I forth to meet thee, Diligently to seek thy face, and I have found thee. 16 I have spread my couch with carpets of tapestry, With striped cloths of the yarn of Egypt. 17 I have perfumed my bed With myrrh, aloes, and cinnamon. 18 Come, let us take our fill of love until the morning; Let us solace ourselves with loves. 19 For the man is not at home; He is gone a long journey: 20 He hath taken a bag of money with him; He will come home at the full moon. 21 With her much fair speech she causeth him to yield; With the flattering of her lips she forceth him along. 22 He goeth after her straightway, As an ox goeth to the slaughter, Or as `one in' fetters to the correction of the fool; 23 Till an arrow strike through his liver; As a bird hasteth to the snare, And knoweth not that it is for his life. 24 Now therefore, `my' sons, hearken unto me, And attend to the words of my mouth. 25 Let not thy heart decline to her ways; Go not astray in her paths. 26 For she hath cast down many wounded: Yea, all her slain are a mighty host. 27 Her house is the way to Sheol, Going down to the chambers of death. . Contrast him with Joseph in Genesis 39 Chapter 39 1 And Joseph was brought down to Egypt; and Potiphar, an officer of Pharaoh's, the captain of the guard, an Egyptian, bought him of the hand of the Ishmaelites, that had brought him down thither. 2 And Jehovah was with Joseph, and he was a prosperous man; and he was in the house of his master the Egyptian. 3 And his master saw that Jehovah was with him, and that Jehovah made all that he did to prosper in his hand. 4 And Joseph found favor in his sight, and he ministered unto him: and he made him overseer over his house, and all that he had he put into his hand. 5 And it came to pass from the time that he made him overseer in his house, and over all that he had, that Jehovah blessed the Egyptian's house for Joseph's sake; and the blessing of Jehovah was upon all that he had, in the house and in the field. 6 And he left all that he had in Joseph's hand; and he knew not aught `that was' with him, save the bread which he did eat. And Joseph was comely, and well-favored. 7 And it came to pass after these things, that his master's wife cast her eyes upon Joseph; and she said, Lie with me. 8 But he refused, and said unto his master's wife, Behold, my master knoweth not what is with me in the house, and he hath put all that he hath into my hand: 9 he is not greater in this house than I; neither hath he kept back anything from me but thee, because thou art his wife: how then can I do this great wickedness, and sin against God? 10 And it came to pass, as she spake to Joseph day by day, that he hearkened not unto her, to lie by her, `or' to be with her. 11 And it came to pass about this time, that he went into the house to do his work; and there was none of the men of the house there within. 12 And she caught him by his garment, saying, Lie with me: and he left his garment in her hand, and fled, and got him out. 13 And it came to pass, when she saw that he had left his garment in her hand, and was fled forth, 14 that she called unto the men of her house, and spake unto them, saying, See, he hath brought in a Hebrew unto us to mock us: he came in unto me to lie with me, and I cried with a loud voice: 15 and it came to pass, when he heard that I lifted up my voice and cried, that he left his garment by me, and fled, and got him out. 16 And she laid up his garment by her, until his master came home. 17 And she spake unto him according to these words, saying, The Hebrew servant, whom thou hast brought unto us, came in unto me to mock me: 18 and it came to pass, as I lifted up my voice and cried, that he left his garment by me, and fled out. 19 And it came to pass, when his master heard the words of his wife, which she spake unto him, saying, After this manner did thy servant to me; that his wrath was kindled. 20 And Joseph's master took him, and put him into the prison, the place where the king's prisoners were bound: and he was there in the prison. 21 But Jehovah was with Joseph, and showed kindness unto him, and gave him favor in the sight of the keeper of the prison. 22 And the keeper of the prison committed to Joseph's hand all the prisoners that were in the prison; and whatsoever they did there, he was the doer of it. 23 The keeper of the prison looked not to anything that was under his hand, because Jehovah was with him; and that which he did, Jehovah made it prosper. . What was the difference between them?
  • Think about how Psalms 119:9 9 BETH. Wherewith shall a young man cleanse his way? By taking heed `thereto' according to thy word. relates to them, and to you.
