Jeremiah 17:9 (CB)

The heart is deceitful above all things, and desperately sick; who can understand it?

“The Devil is one of the ‘things.’ There is within our nature that which would send the best to hell if Sovereign Grace did not prevent. There is a little hell within the heart of every child of God, and only the great God of heaven can master that mischievous indwelling sin.” -Charles Spurgeon
