Jesus Christ stated that the greatest demonstration of love is giving up one's own life on behalf of others (John 15:13). That is precisely what He did for us when He made atonement for our sin on the cross. Now, the Jehovah's Witnesses do not believe that Jesus is God. In order to remain consistent with their theology, they must accept the idea of a creature doing a greater act of love than the Creator Himself because it was the former who laid down His own life in our place. The Trinity is the solution to this dilemma. If Jesus Christ is the second Person of the Godhead, then it is God who has made the greatest possible demonstration of love.
