Communion with Christ rests on three things—seeing him by faith, living upon his life, and experiencing his manifested presence. But all these three things depend on his resurrection and a knowledge of its power. As risen from the dead, the saints see him; as risen from the dead, they live a life of faith upon him; as risen from the dead, he manifests himself unto them; and as life and feeling spring up in their souls from sweet communion with him, the power of his resurrection becomes manifest in them.
This communion, therefore, with the Lord Jesus as a risen Head all the reconciled and justified saints of God are pressing forward after, according to the measure of their grace and the life and power of God in their soul. It is indeed often sadly interrupted and grievously broken through by the sin that dwelleth in us. But the principle is there, for that principle is life; and life is the privilege, the possession, and the distinction of the children of God.
You need none to assure you that Jesus is risen from the dead if he manifests himself to your soul. You want no evidence that you are a sheep if you have heard and know his voice. So you may say, "Jesus is risen, for I have seen him; Jesus is risen, for I have heard him; Jesus is risen, for I live upon him." Communion with Jesus is the life of religion, and indeed without it religion is but an empty name. If without him we can do nothing; if he is our life, our risen covenant Head, our Advocate with the Father, our Husband, our Friend, our Brother, how are we to draw sap out of his fulness, as the branch from the vine, or to know him personally and experimentally in any one of his endearing relationships, unless by continual communion with him on his throne of grace?
In fact, this is the grand distinguishing point between the living and the dead, between the true child of God and the mere professor, that the one has real union and communion with a risen Jesus, and the other is satisfied with a form of godliness. Every quickened soul is made to feel after the power of God, after communion from above, after pardon and peace, after visitations of mercy and grace; and when he has had a view of Christ by faith, and some revelation of his Person and work, grace and glory, nothing afterwards can ever really satisfy him but that inward communion of spirit with Jesus whereby the Lord and he become one; "for he that is joined to the Lord is one spirit."
