God sent His Son Jesus Christ into the world so that our sins could be forgiven. Jesus lived a perfect life and He healed and loved people and taught them about God. He was put to death like a common criminal on a cross of wood.
When He died, He willingly took the sins of the world — yours and mine — and paid the penalty in our place. “For God so loved the world that He gave His one and only Son, that whoever believes in Him would not perish, but would have everlasting life.”
