Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” John 8:12
Religion is meant to be in everyday life a thing of unspeakable joy. And why do so many complain that it is not so? Because they do not believe that there is no joy like the joy of abiding in Christ and in His love, and being branches through whom He can pour out His love on a dying world.
Andrew Murray, The True Vine
When a new graft is placed in a vine and it survives there, there is a twofold process that takes place. The first is in the wood. The graft shoots its little roots and fibers down into the stem, and the stem grows up into the graft, and what has been called the structural union is affected. The graft abides and becomes one with the vine, and even though the vine were to die, would still be one wood with it. Then there is the second process, in which the sap of the vine enters the new structure, and uses it as a passage through which sap can flow up to show itself in young shoots and leaves and fruit. Here is the vital union. Into the graft that abides in the stock, the stock enters with sap to abide in it.
When our Lord says: “Abide in me, and I in you,” He points to something analogous to this. “Abide in me”: that refers more to that which we have to do. We have to trust and obey, to detach ourselves from all else, to reach out after Him and cling to Him, to sink ourselves into Him. As we do this, through the grace He gives, a character is formed and a heart prepared for the fuller experience: “I in you.” God strengthens us with might by the Spirit in the inner man, and Christ dwells in the heart by faith.
