“How can I know all the sins lurking in my heart? Cleanse me from these hidden faults. Keep your servant from deliberate sins! Don’t let them control me. Then I will be free of guilt and innocent of great sin.“
Psalm 19:12-13 NLT
David had a thought that worried him. He wanted to be pure and sinless before God but was concerned about sins “lurking in [his] heart” that were hidden. But were they sins that only he knew about or were they sins that he was unaware of? I think it was the former. Regarding the latter, there are sins that we may be unaware of, but we can be assured that the Holy Spirit and God’s Word will bring these to our consciousness sooner or later. And in the end all sin will be exposed. Jesus said, “For all that is secret will eventually be brought into the open, and everything that is concealed will be brought to light and made known to all” (Luke 8:17).
Believers may be conscious of their hidden sins but rationalise hiding them because they think that they are just personal and no one else is involved or hurt by them. But sin is sin and will emerge eventually. God gives us time to deal with our sins, through repentance and forgiveness, but if left too long, then in love He will engineer circumstances that cause us to face the gravity of the sins and force us to deal with them. We should note that dealing with sin involves repentance, where we don’t just confess our sins, but we turn away from them, never to commit them again. The confessing of sins without repentance is not really dealing with them. Being remorseful usually happens when someone is caught red handed in their sin. But there is some sinful behaviour that will take a lifetime to sort out because it involves character traits that need to be controlled. James highlighted the dangers of an uncontrolled tongue. “And among all the parts of the body, the tongue is a flame of fire. It is a whole world of wickedness, corrupting your entire body. It can set your whole life on fire, for it is set on fire by hell itself. … And so blessing and cursing come pouring out of the same mouth. Surely, my brothers and sisters, this is not right!” (James 3:6, 10). Perhaps repentance for a tongue “set on fire by hell itself” will take time as Holy Spirit refines and guides.
Paul struggled with sin, as we read in Romans 7, “And I know that nothing good lives in me, that is, in my sinful nature. I want to do what is right, but I can’t. … I have discovered this principle of life—that when I want to do what is right, I inevitably do what is wrong. I love God’s law with all my heart. But there is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me” (Romans 7:18, 21-23). But Paul continued, “Thanks be to God, who delivers me through Jesus Christ our Lord! So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin. Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death” (Romans 7:25-8:2). That must be worth a “Hallelujah!” or two this morning.
David asked God to cleanse him from the sins lurking in his heart, because he said he will then be “free of guilt and innocent of great sin.” Through the blood of Jesus we too are cleansed from all our sins. 1 John 1:7, “But if we are living in the light, as God is in the light, then we have fellowship with each other, and the blood of Jesus, his Son, cleanses us from all sin.” Andraé Crouch wrote a song, “The blood that Jesus shed for me … will never lose its power“. And a hymn written by William Cowper many years ago reads, There is a fountain filled with blood , Drawn from Immanuel’s veins; And sinners, plunged beneath that flood, Lose all their guilty stains:” David didn’t know the redeeming power of Jesus’ shed blood but his relationship with God was such that he knew where he could go to be cleansed from his sins. We are indeed a blessed people today, living as we do in this season of God’s grace.
Father God. We thank You for Your grace and love. We confess our sins to You today, confident in the redeeming power of Jesus’ atoning sacrifice. We worship You today. Amen.
