Jeremiah 17:9 "The heart is deceitful above all things, and desperately wicked: who can know it?"
John 3:16 & 17 "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved."
Follow your own heart to death, but God's heart is clearly life.
