Psalms 66:18-19

If I had regarded iniquity in my heart,

The Lord would not hear:

But verily God hath heard.

Hypocrisy disqualifies the suppliant, but he is confident that he is no hypocrite, and the answer to his prayer justifies him. There is no self-righteousness in this, but the simplicity of "a conscience void of offence toward God and men." Cp. Hezekiah's plea, Isaiah 38:3; and Psalms 17:1 ff; Psalms 18:20 ff; Job 16:17; Isaiah 1:15; Isaiah 59:2-3; 1 John 3:21; &c.; and Isaiah 1:13 (R.V.), "I cannot away with iniquity and the solemn meeting"; i.e. tolerate the union of religious observances and iniquitous conduct.
