Thou wilt keep him in perfect peace, whose mind is stayed on Thee: because he trusteth in Thee. – Isaiah 26:3

There are many of us who could say, without any exaggeration, that though we do not think so much of our Lord as we should, and are not so much with Him in contemplation as we desire, yet we have spent more time with Him than we have spent with anybody else. Little as we know compared with what we hope to know, yet His love has become to us now the brightest, the most conspicuous fact in all our history. We know but few things; but we know that we are one with Christ in a union never to be broken.

If we are one with Him, to live with Him should be the most natural thing in our lives. Have I not heard, however, of some professors who have not had communion with Christ for many a day? I talked once with a brother, who said a great deal about many things; and when he had complained of this and of that, I leant forward to him, and said, “Brother, how long is it since you have had close fellowship with Christ?” He answered, “Oh, there you have got me!” When I asked him, “What do you mean by that?” he answered, “I am afraid that I have not had fellowship with Christ for months.” I had suspected that it must have been so, or else his conversation would not have been of the kind it was. What a sad thing it must be for a wife to live in her husband’s house, and not speak to him for weeks! But how much worse it is for us to profess to be one with Christ, and yet have no sort of communication with Him by the month together! This is something perfectly horrible. God save us all from such a thing! May we think continually of our Lord, and ever live with Him, because we are one with Him! ~ C.H. Spurgeon
