Iniquity is hidden sin, a sin you have covered or you are covering/hiding.
When David sinned, instead of running to God, he tried to cover/hide his sin thus the sin became an iniquity.
Reason David in entire Book of Psalms is crying to God to forgive him his iniquity.
Psalms 32:5 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.
Iniquity is also deliberate sin. Deliberately purposing in the heart to do evil.
The people who wanted to stone the woman caught in adultery all had iniquities – sins they were covering/hiding. But meeting Jesus, their iniquities were uncovered as He said,
‘Let any one of you who is without sin be the first to throw a stone at her’ (John 8:7).
Iniquity indicates a conscious decision; to commit iniquity is to proceed without repentance. Micah 2:1 says, “Woe to those who plan iniquity, to those who plot evil on their beds! At morning’s light, they carry it out because it is in their power to do it.” In David’s psalm of repentance, he cries out to God, saying, “Wash away all my iniquity and cleanse me from my sin” (Psalm 51:2).
God forgives iniquity, as He does any sort of sin when we genuinely repent (Hebrews 8:12). However, iniquity left unchecked advances to a point of intentional sin with no fear of God. The growth of shameless sin is sometimes portrayed as a “cup of iniquity” being filled to the brim (Revelation 17:4). This often pertains to nations who have forsaken God entirely.
Before you cry to The lord, know that he knows truly whom you are.
Forgive me, oh Lord for everything that I have done. Jesus, please hear my prayers.
