God did not send Jesus into the world just to have something to do or for fun. A great need of vital importance came into existence and man could not fulfill it because he harbors thoughts, words and deeds that are sinful.
So much so that if our precious Lord had not been sent to us, we would all be damned. The most powerful possession in the world is love.
God proved his love by sending Jesus. Jesus proved his love by willingly hanging on that old rugged cross bearing all of our sins.
It doesn't stop there. We must believe this, accept it and take Him into our hearts as Savior and learn of Him, and what he expects us to do, and do it to show Him our love and appreciation for His great sacrifice.
