This it is to 'grow into the grace of our Lord and Saviour'; a deeper consciousness of His love creeping round the roots of my heart every day, and fuller possession of His gifts placed in my opening hand every day; and a continual approximation to the beauty of His likeness, which never halts nor ceases.
'Grow in the knowledge of our Lord and Saviour.' The knowledge of a person is not the same as the knowledge of a creed or of a thought or of a book. We are to grow in the knowledge of Christ, which includes but is more than the intellectual apprehension of the truths concerning Him. He might turn the injunction into--'Increase your acquaintance with your Saviour.' Many Christians never get to be any more intimate with Him than they were when they were first introduced to Him. They are on a kind of bowing acquaintance with their Master, and have little more than that. We sometimes begin an acquaintance which we think promises to ripen into a friendship, but are disappointed. Circumstances or some want of congeniality which is discovered prevent its growth. So with not a few professing Christians. They have got no nearer Jesus Christ than when they first knew Him. Their friendship has not grown. It has never reached the stage where all restraints are laid aside and there is perfect confidence. 'Grow in the knowledge of your Lord and Saviour Jesus Christ.' Get more and more intimate with Him, nearer to Him, and franker and more cordial with Him day by day.
But there is another side to the injunction besides that. We are to grow in the grasp, the intellectual grasp and realisation of the truths which lie wrapped up and enfolded in Him. The first truths that a man learns when he becomes a Christian are the most important. The lesson that the little child learns contains the Omega as well as the Alpha of all truth. There is no word in all the gospel that is an advance on that initial word, the faith of which saves the most ignorant who trusts to it. We begin with the end, if I may say so, and the highest truth is the first truth that we learn. But the aspect which that truth bears to the man when, first of all, it dawns upon him, and he sees in it the end of his fears, the cleansing of his heart, the pardoning of his sins, his acceptance with God, is a very different thing from the aspect that it ought to wear to him, after, say forty years of pondering, of growing up to it, after years of experience have taught him. Life is the best commentary upon the truths of the gospel, and the experience teaches their depths and their power, their far-reaching applications and harmonies. So our growth in the knowledge of Jesus Christ is not a growing away from the earliest lessons, or a leaving them behind, but a growing up to and into them. So as to learn more fully and clearly all their infinite contents of grace and truth. The treasure put into our hands at first is discovered in its true preciousness as life and trial test its metal and its inexhaustibleness. The child's lesson is the man's lesson. All our Christian progress in knowledge consists in bringing to light the deep meaning, the far-reaching consequences of the fact of Christ's incarnation, death, and glory. 'God so loved the world that He gave His only begotten Son that whosoever believeth in Him should not perish, but have everlasting life.' The same truth which shone at first a star in a far-off sky, through a sinful man's night of fear and agony, grows in brilliance as we draw nearer to it, until at last it blazes, the central Sun of the Universe, the hearth for all vital warmth, the fountain of all guiding light, the centre of all energy. Christ in His manhood, in His divinity, Christ in His cross, resurrection, and glory, is the object of all knowledge, and we grow in the knowledge of Him by penetrating more deeply into the truths which we have long ago learned, as well as by following them as they lead us into new fields, and disclose unsuspected issues in creed and practice.
