“The heart is deceitful above all things, and desperately sick; who can understand it? “I the Lord search the heart and test the mind, to give every man according to his ways, according to the fruit of his deeds.” …O Lord, the hope of Israel, all who forsake you shall be put to shame; those who turn away from you shall be written in the earth, for they have forsaken the Lord, the fountain of living water. Heal me, O Lord, and I shall be healed; save me, and I shall be saved, for you are my praise.”
Jeremiah 17:9-10, 13-14 ESV
