The Power of Knowing

A devotional by John Piper for reading on October 25th

“…And you will know the truth, and the truth will set you free.” ( John 8:32 32 and ye shall know the truth, and the truth shall make you free. )

It is remarkable that again and again the apostle Paul confronts failure to do what’s right with failure to know what’s right. For example:

Right Knowing Prevents Continuing in Sin

Are we to continue in sin that grace might increase? May it never be! ... or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? ( Romans 6:1 Chapter 6 1 What shall we say then? Shall we continue in sin, that grace may abound? –3)

Right Knowing Prevents the Prostituting of Grace

Shall we sin because we are not under law but under grace? May it never be! Do you not know that when you present yourselves to someone as slaves for obedience, you are slaves of the one whom you obey, either of sin resulting in death, or of obedience resulting in righteousness? ( Romans 6:1 Chapter 6 1 What shall we say then? Shall we continue in sin, that grace may abound? 5–16)

Right Knowing Prevents Boasting

Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough? ( 1 Corinthians 5:6 6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump? )

Right Knowing Empowers Good Dispute Settling

Or do you not know that the saints will judge the world? And if the world is judged by you, are you not competent to constitute the smallest law courts? Do you not know that we shall judge angels? How much more, matters of this life? ( 1 Corinthians 6:2 2 Or know ye not that the saints shall judge the world? and if the world is judged by you, are ye unworthy to judge the smallest matters? )

Right Knowing Prevents Fornication

Do you not know that your bodies are members of Christ? Shall I then take away the members of Christ and make them members of a harlot? May it never be! Or do you not know that the one who joins himself to a harlot is one body with her? For he says, “The two will become one flesh.” … do you not know that your body is a temple of the Holy Spirit who is in you, who you have from God, and that you are not your own? ( 1 Corinthians 6:15 15 Know ye not that your bodies are members of Christ? shall I then take away the members of Christ, and make them members of a harlot? God forbid. –19)

Therefore, don’t coast in your thinking. Don’t be passive with your mind.
