Never listen to that fatal lie, that to be a man means of necessity to be always a sinner; that humanity is only another word for irreclaimable desert or irreparable despair. When the enemy of your soul whispers to you out of his lying heart that because sin has found one of its strongholds in the appetites and propensities of your poor body, or in the original perversity of a rebellious spirit, and that you cannot be expected to triumph over that evil nature because it _is_ your nature, remember Bethlehem, and answer him with the promise of God, "_I will dwell in you, and walk in you_." It was because He purposed to cleanse wholly, body and soul and spirit, that He came, taking the body, soul, and spirit of a man, and that He will come again, taking your body, soul, and spirit as His dwelling-place. III. The birth and childhood of Jesus were the beginning of His great sacrifice, as well as the preparation for it. The spirit of Bethlehem and the spirit of Calvary are one. He was born for others that He might die for others. The mystery of God in the Babe was the beginning of the mystery of God on the cross. The one was a part of the other. If they had not "laid Him in a manger" for us, they could never have laid Him in the tomb, that He might "taste death for every man." And it was because "He grew, and waxed strong in spirit, and increased in wisdom, and the grace of God was upon Him" in those early years, that He was able afterwards to tread the winepress alone, to work out a perfect example of manhood, to wrestle with Death and the Grave, and finally to stand forth for us as the great Victorious One, conqueror of all our foes. And is it not in this same fashion and for this same purpose that Christ is to be formed in us? "_He grew_." Progress is the law of happiness, the law of holiness, the law of life. To stand still is to die. It was not enough for the fulfilment of His great mission that He should be born, that He should live--He must grow. Let us take that lesson to our hearts, in this superficial, painted, rushing generation. Let us beware of resting our hope to satisfy the eternal claims of God upon some great event in our spiritual history of long ago. It is not enough to have been converted. It is not enough to have had the adoption of the Father. It is not enough to have entered the spiritual family of Christ. It is not enough that even Jesus revealed Himself in us. Thousands of false hopes are built on these past events, which, divinely wrought as they may have been, have ceased to possess any vital connexion with the life and character of to-day. Such a religion is a religion of memory, destined to be turned in the presence of the Throne to unmixed remorse. But how, and in what, are we to grow? In manner and in substance like our Lord. Jesus grew in strength and stature, in wisdom and in grace--the grace of God was upon Him.
