But who can discern their own errors? Forgive my hidden faults. Keep your servant also from willful sins; may they not rule over me. Then I will be blameless, innocent of great transgression. May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer (NIV).
As we consider the subject of secret sins, we come to a fourth point. The person who knows the Lord has confidence in the grace and compassion of the Lord. This is the confidence in God that is part of the essence of faith. Here we see a believer that has sinned freely confessing hidden sins to his or her God. But why does the believer confess them? We do because we know that God is ready to receive us, to help us in our weaknesses, to blot out even the stain unseen. Make no mistake, people set apart for God take their sins seriously, because God is very serious in our lives. (In other words, we fear God.) But we also have a large view of the magnitude of redeeming love, and so we ask for forgiveness! However, there is more to our war against remaining sin.
Keep your servant also from willful sins…. The law covenant recognized two categories of sins: unintentional and defiant (Numbers 15:27-31). The law covenant made provision for a sacrificial covering for those who sinned unintentionally. However, there was no sacrifice provided for those who sinned defiantly or willfully. The law had only one word for any such sinner: death. Since David lived under the law covenant, he was concerned not to bring the force of God’s law upon his head. Compare 1 Corinthians 15:56: The sting of death is sin, and the power of sin is the law (ESV). So, David prayed that God would keep him from such sins. It is good and wise that we pray for God’s help in spiritual warfare. In the new covenant, we have the Holy Spirit as our Helper against sin (cf. Galatians 5:16-26).
David continued with the plea may they not rule over me. Again, we must remember that David is praying as an old covenant believer. In many areas, our spiritual experience is similar to those who lived under the law. But in others, we must never underestimate the difference that Christ established in his new and better covenant. We must understand this phrase used by David carefully, because what David prayed for under the law, we now possess in the new covenant. For sin shall not be your master, because you are not under law, but under grace (Romans 6:14). “What he [David] there [Psalm 19:13] so earnestly prays for, the apostle in the words of the text [Rm 6:14] promiseth unto all believers, by virtue of the grace of Christ Jesus administered in the gospel [the new covenant].” [Owen, Works, Vol. 7, p. 506.] Having said this, we must carefully consider the following facts:
- Sin still continues in new covenant believers (Romans 13:14; Galatians 5:17; 1 Peter 2:11). Sin still continues to incite us to rebellion against God and to break his commands. In this way sin has lost none of its character as sin, whether one has been a Christian five minutes or fifty years. Sin is still deceptive and persistent.
- Yet sin is a weakened force in believers. Though it is still sin, it is unable to rise to dominate the inner person of the heart of the believer. There is a new master in the heart, the reigning grace of Jesus Christ the Lord (Romans 5:21; 6:15-22).
- Though sin is weakened in believers, it still strives for domination. We are still in a war against sin. Dear friends, I warn you as “temporary residents and foreigners” to keep away from worldly desires that wage war against your very souls (1 Peter 2:11 NLT). And since we are in a war, we need to make use of every kind of privilege and spiritual armor that God has given us to fight sin (Ephesians 6:10-18).
“This is one principal difference between the law [the old covenant] and the gospel [the new covenant], and was ever so esteemed in the church of God, until all communication of efficacious grace began to be called in question: The law guides, directs, commands, all things that are against the interest and rule of sin. It judgeth and condemneth both the things that promote it and the persons that do them; it frightens and terrifies the consciences of those who are under its dominion. But if you shall say unto it, ‘What then shall we do? this tyrant, this enemy, is too hard for us. What aid and assistance against it will you afford unto us? what power will you communicate unto its destruction?’ Here the law is utterly silent, or says that nothing of this nature is committed unto it of God; nay, the strength it hath it gives unto sin for the condemnation of the sinner: ‘The strength of sin is the law.’ But the gospel, or the grace of it, is the means and instrument of God for the communication of internal spiritual strength unto believers. By it do they receive supplies of the Spirit or aids of grace for the subduing of sin and the destruction of its dominion. By it they may say they can do all things, through Him that enables them” (Owen, Works, Vol. 7, pp. 546-547, my emphasis).
Grace and peace, David
