To put on the Lord Jesus is to be clothed with the very best robe. This robe makes us look better than we really are. But when we are dressed with the best we begin to act differently. Having put on the Lord Jesus, we are clothed with Him and His character replaces our character. His Life is received in exchange for our life. If we cooperate with the Life we will naturally find our behavior is changed.
But what of the elder son? “Son, you are always with me, and all that I have is yours” (Luke 15:31). Hallelujah! There is no partiality with God, however much we may think God is being more fair or more generous to some brother or sister. Not so: the robe, the ring, and the shoes only represent the “all,” the fullness of the Father, and “of His fullness we have all received” (John 1:16). The Father says, “All that I have is yours!” Who can dare ask God for a single thing apart from the Son?
