The heart is considered to be the essence of a man. The fount of a person’s thinking, personality and being is their heart. Proverbs 23:7a says: “For as he thinks in his heart, so is he.” We know that the heart is evil until we are given a new heart by God.
It is not difficult to have a “change of heart”. Deuteronomy 4:29: “But from there you will seek the Lord your God and you will find Him if you seek Him with all your heart and with all your soul”. God doesn’t want anyone to perish. He is waiting for sinners to seek Him for a new heart.
I like the way an old hymn says it: “Softly and tenderly Jesus is calling, Calling for you and for me. See on the portals He’s waiting and watching, Watching for you and for me. Come home, come home, Ye who are weary, come home. Earnestly, tenderly Jesus is calling, Calling, ‘O sinner, come home’!”
We can have “stinkin’ thinkin’” in our heart. Psalm 14:1: The fool has said in his heart, ‘There is no God’. They are corrupt; They have done abominable works; There is none who does good.”
Praise God! He is the only One who can give a new heart!
