“I in them.” – John 17:23, 26
“I in them.” It is the most blessed word I know of. You, beloved, need not go abroad to find the Lord Jesus Christ. Where does He live? He lives within you. “I in them.” As soon as ever you pray you are sure He hears you, because He is within you. He is not knocking at your door: He has entered into you, and there He dwells, and will go no more out for ever.
What a blessed sense of power this gives to us. “I in them.” Then it is no more “I” in weakness, but, since Jesus dwells in me, “I can do all things through Christ that strengtheneth me.” “I in them.” It is the glory of the believer that Christ dwells in him. “Unto you that believe He is precious.”
Hence we gather the security of the believer. Brother, if Christ be in me, and I am overcome, Christ is conquered too, for He is in me. “I in them.” I cannot comprehend the doctrine of believers falling from grace. If Christ has once entered into them, will He not abide with them? Paul saith, “I am persuaded that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God which is in Christ Jesus our Lord.” To that persuasion I set my hand and seal. Well, then, if Christ is in us, whatever happens to us will happen to Him. If it is an indissoluble union-and so He declares it is-“I in them,” then His destiny and ours are linked together; and if He wins the victory we conquer in Him: if He sits at the right hand of God we shall sit at the right hand of God with Him, for He is in us. ~ C.H.
