If I regard iniquity in my heart, the Lord will not hear me:
If I regard iniquity in my heart the Lord will not hear me - rather 'If I had regarded iniquity in my heart, the Lord would not have heard me' (Job 35:12-13; Isaiah 1:15; Isaiah 59:2-3; John 9:31; 1 John 3:22). Integrity of aim, with purity as to secret or open sin and habitual hypocrisy, not absolute sinlessness, is meant.
