“Therefore also now, saith the Lord, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning:”
Lord knows our hearts
“Every way of a man is right in his own eyes: but the Lord pondereth the hearts.”
Draw nigh to God
“Draw nigh to God, and He will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded.”
