1 Blessed is the one whose transgression is forgiven, whose sin is covered. 2 Blessed is the man against whom the LORD counts no iniquity, and in whose spirit there is no deceit. 3 For when I kept silent, my bones wasted away through my groaning all day long. 4 For day and night your hand was heavy upon me; my strength was dried up as by the heat of summer. Selah 5 I acknowledged my sin to you, and I did not cover my iniquity; I said, “I will confess my transgressions to the LORD,” and you forgave the iniquity of my sin. Selah —Psalm 32:1-5

While David keeps silent about his sin, his sin is loud. Sin has an echo and that echo reverberates louder the more you try to stifle it. David’s silence is an attempt at “deceit” (cf. v. 2). It is an attempt to “cover” (cf. v. 5). But our coverings of fig leaves don’t hide nuthin’.
When God’s children are silent, something is wrong. Silence is an attempt to muffle the echo of sin. John Goldingay comments, “Keeping quiet is not a mark of OT piety. OT piety makes noise, either in lament and prayer or in thanksgiving and praise. There is something suspicious about a person keeping quiet. It gives the impression that something is being concealed.” When the kids are silent, parents suspect. When God’s children are silent, God knows. Our silence doesn’t keep God in ignorance. It shouts to our own knowledge of our guilt.
Worse still, our silence is blasphemous. Our silence says we think God is a fool. We play mute thinking we’ve made God blind and deaf. We think ourselves more sly than God is wise. By silently denying our sin, we call God a liar. 1 John 1:10 – “If we say we have not sinned, we make him a liar, and his word is not in us.” Silence on sin is sin doubled down. We dishonor God by our rebellion and then we blaspheme Him with our ridiculing silence.
The only way to silence the echo of our sin is to let it reverberate to heaven with confession. The only way to cover sin, is to uncover it. Try to cover your sin, and it will be exposed by judgment or chastisement. Expose it, and it will be covered by mercy and grace. When you stop trying to cover your own sin, God will cover it. He will cleanse you by the shed blood of Christ and cover you with the robe of His righteousness.
