Galatians 6:1 (KJV), “Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.”

Verse 7-8, “Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.  For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.”

Jesus says in John 3:16 (NIV), “For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life.”
