The doctrine of the divine indwelling is one of the most important in the New Testament, and its meaning for the individual Christian is precious beyond all description. To neglect it is to suffer serious loss. The apostle Paul prayed for the Ephesian Christians that Christ might dwell in their hearts by faith. Surely it takes faith of a more than average vitality to grasp the full implications of this great truth. Two facts join to make the doctrine difficult to accept: the supreme greatness of God and the utter sinfulness of man. Those who think poorly of God and well of themselves may chatter idly of "the deity within," but the man who trembles before the high and lofty One that inhabiteth eternity, whose name is Holy, the man who knows the depth of his own sin, will detect a moral incongruity in the teaching that One so holy should dwell in the heart of one so vile. But however incongruous it may appear to be, in the Holy Scriptures it is taught so fully that it cannot be overlooked and so plainly that it can hardly be misunderstood. "If a man love me," said our Lord Jesus Christ, "he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him" (John 14:23). That this abiding is within the man is shown by these words: "At that day ye shall know that I am in my Father, and ye in me, and I in you" (14: 20). Christ said of the Holy Spirit: "He ... shall be in you" (14: 17), and in His great prayer in John 17 our Lord twice used the words "I in them."
