Iniquity
Iniquity refers to a premeditated choice; to commit iniquity is to continue without repentance. David’s sin with Bathsheba that led to the killing of her husband, Uriah, was iniquity (2 Samuel 11:3–4; 2 Samuel 12:9). 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 type of sin when we repent (Jeremiah 33:8; Hebrews 8:12). However, iniquity left unchecked leads to a state of willful sin with no fear of God. The build-up of unrepentant sin is sometimes pictured as a “cup of iniquity” being filled to the brim (Revelation 17:4; Genesis 15:16). This often applies to nations who have forsaken God completely. Continued iniquity leads to unnatural affections, which leads to a reprobate mind. Romans 1:28–32 outlines this digression in vivid detail. The sons of Eli are biblical examples of reprobates whom God judged for their iniquities (1 Samuel 3:13–14). Rather than repent, Eli’s sons continued in their abominations until repentance was no longer possible.
