We might hear people say, "Follow your heart," or "God knows my heart" or even "Give God your heart." The Bible says: "The heart is deceitful above all things, and desperately wicked; who can know it?" (Jeremiah 17)
God is not interested in receiving the corrupt heart of any man. Many don't realize that by nature, we CANNOT do good. Some may do what appears to be "good", but those things are as FILTHY RAGS before God (Isaiah 64), UNLESS those deeds are the fruit of the VINE, Christ (John 15).
But HERE is our hope, not that we reach for God, to GIVE Him anything . He sees things as they are, reaches down to humanity, to make us clean and make us new, by His will, for His glory.
"Then WILL I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, WILL I cleanse you. A new heart also WILL I GIVE you, and a new spirit WILL I put within you: and I WILL take away the stony heart out of your flesh, and I WILL give you a heart of flesh. And I WILL put my spirit within you, and CAUSE you to walk in my statutes..." ~Ezekiel 36
Now we are commanded to repent and believe the Gospel: That Christ, fully God and fully man, paid for the sins of His people, dying and rising again the third day, so that we could be cleansed and covered by HIS RIGHTEOUSNESS. Those who DO NOT believe are under condemnation (John 3), BECAUSE their hearts are exactly as they were when they were born, DESPERATELY WICKED.
Christ is our ONLY HOPE to have a new heart. I urge you, and God commands: Repent (Acts 17) and believe! Those who have been given a NEW heart WILL!
