The definition of iniquity is immoral or grossly unfair behavior. Some of the synonyms are: wickedness, sinfulness, immorality, impropriety, vice, evil, sin.  We are all guilty of this and when we accept this, we can experience true forgiveness for people who have abused us sexually as well as give the Lord the Honor, Praise, and Glory for His forgiveness toward us for our rebelling against Him and loving immoral behavior, ideas, and concepts instead of Him.
