The Heart is Deceitful

The heart is deceitful above all things and beyond cure. Who can understand it? – Jeremiah 17:9

Above all else, guard your heart, for everything you do flows from it. – Proverbs 4:23

Rather, clothe yourselves with the Lord Jesus Christ, and do not think about how to gratify the desires of the flesh. – Romans 13:14

Here then, is one striking evidence of the deceitfulness of the heart. It produces ignorance of ourselves; it keeps men strangers to their own character; and makes them fatally presume that they are in friendship with God, while they are enemies to Him in their minds and by wicked works. ~from THE DECEITFULNESS OF THE HEART by David Black
