'He exhorted them all, that with purpose of heart they would cleave unto the Lord.' The first thing that strikes one about this all-sufficient directory for Christian life is the emphasis with which it sets forth 'the Lord' as the one object to be grasped and held. The sum of all objective Religion is Christ--the sum of all subjective Religion is cleaving to Him. A living Person to be laid hold of, and a personal relation to that Person, such is the conception of Religion, whether considered as revelation or as inward life, which underlies this exhortation. Whether we listen to His own words about Himself, and mark the altogether unprecedented way in which He was His own theme, and the unique decisiveness and plainness with which He puts His own personality before us as the Incarnate Truth, the pattern for all human conduct, the refuge and the rest for the world of weary ones; or whether we give ear to the teaching of His Apostles; from whatever point of view we approach Christianity, it all resolves itself into the person of Jesus Christ. He is the _Revelation_ of God; theology, properly so called, is but the formulating of the facts which He gives us; and for the modern world the alternative is, Christ the manifested God, or no God at all, other than the shadow of a name. He is the perfect _Exemplar_ of humanity! The law of life and the power to fulfil the law are both in Him; and the superiority of Christian morality consists not in this or that isolated precept, but in the embodiment of all goodness in His life, and in the new motive which He supplies for keeping the commandment. Wrenched away from Him, Christian morality has no being. He is the sacrifice for the world, the salvation of which flows from what He does, and not merely from what He taught or was. His personality is the foundation of His work, and the gospel of forgiveness and reconciliation is all contained in the name of Jesus. There is a constant tendency to separate the results of Christ's life and death, whether considered as revelation, atonement, or ethics, from Him, and unconsciously to make these the sum of our Religion, and the object of our faith. Especially is this the case in times of restless thought and eager canvassing of the very foundations of religious belief, like the present. Therefore it is wholesome for us all to be brought back to the pregnant simplicity of the thought which underlies this text, and to mark how vividly these early Christians apprehended a living Lord as the sum and substance of all which they had to grasp.
