Psalm 32:1 Blessed is he whose transgressions are forgiven, whose sins are covered.2 Blessed is the man whose sin the LORD does not count against him and in whose spirit is no deceit.3 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 sapped as in the heat of summer. "Selah"5 Then I acknowledged my sin to you and did not cover up my iniquity. I said, "I will confess my transgressions to the LORD"-- and you forgave the guilt of my sin. "Selah"6 Therefore let everyone who is godly pray to you while you may be found; surely when the mighty waters rise, they will not reach him.
Verse 3 isn't speaking of just not talking -- David here is talking about when we choose to ignore our sin and leave it un-confessed before God. Sin that is not dealt with works death in us, spiritually.
Romans 5:21 so that, just as sin reigned in death, so also grace might reign through righteousness to bring eternal life through Jesus Christ our LORD.
So, let's talk to God, tell him our sins, faults of character, bad habits, attitudes, and everything that wants to hide from the light of the Word. Let the Word shine in our hearts; His blood was shed for just such a purpose - to heal all our wounds and sins, making us pure and whole, covering us with garments of righteousness.
Ephesians 5:11 Have nothing to do with the fruitless deeds of darkness, but rather expose them. 12 For it is shameful even to mention what the disobedient do in secret. 13 But everything exposed by the light becomes visible, 14 for it is light that makes everything visible. This is why it is said: "Wake up, O sleeper, rise from the dead, and Christ will shine on you."
Please don't be afraid of the Lord's anger. All His anger was taken out on our Lord Jesus when he suffered on the cross for us. He is no longer angry with us, if we humbly come before Him in our weakness.
He will give you strength to overcome!
Psalm 32:11 Rejoice in the LORD and be glad, you righteous; sing, all you who are upright in heart!
Yes, rejoice, because you are clean!
