Coming to Him as to a living stone, rejected indeed by men, but chosen by God and precious… – 1 Peter 2:4

The architect, in placing the stone, was following out his plan. He planned the foundation and thought of every course; and the stone is essential to the wall, even as the foundation is essential to the stone. Thus, we are one with Christ in the design of God. Reverently we say it, that God’s purpose comprehends not only Christ, but the whole company of His elect; and without His chosen people, the design of Jehovah can never be accomplished. He is building a temple to His praise; but a temple cannot be all foundation. There is a necessity for every stone in the wall; in the divine purpose, there is a necessity that such a one should be a living stone, and such a one should be another living stone. The weakest and the meanest of the Lord’s people are as necessary as the noblest and the most beautiful, though indeed all are without any praise until they are built into the wall. He that chose Christ, chose all His people; He arranged that they should be built up together, and in Him “all the building fitly framed together groweth unto an holy temple in the Lord.” Oh, I like to think of each one of us, however insignificant we may appear to be, as being bricks or stones in that great temple of almighty grace! Perhaps some of us may stand where everybody can see us; but what does it matter? If we are in the wall at all, it is well. Wherever you are placed, we are joined to Christ; and therefore no one has a pre-eminence over any other, because we are all alike built upon the one foundation, even Jesus Christ our Lord, into whom we daily grow, pressing closer and closer to Him in experience, and holding tighter and tighter to Him by faith. ~ C.H.
