The metaphor seems to be abandoned in the last words of our text, but it is only apparently so. 'He that believeth shall not make haste.' So, then, we build by believing. The act of building is simple faith in Jesus Christ. We _come_ to Him, as the Apostle Peter has it in his quotation of this text--come to Him as unto a living stone, and the coming and the building are both of them metaphors for the one simple thing, trust in the Lord. The bond that unites men on earth with Christ in Heaven, is the exercise of simple faith in Him. By it they come into contact with Him, and receive from Him the security and the blessing that He can bestow. Nothing else brings a man into living fellowship with Him. When we trust in the Lord we, as it were, are bedded into Him; and resting upon Him with all our weight, then we are safe. That confidence involves the abandonment of all the 'refuges of lies.' There must be utter self-distrust and forsaking and turning away from every dependence upon anything else, if we are to trust ourselves to Jesus Christ. But the figure of a foundation which gives security and stability to the stones laid upon it, does not exhaust all the blessedness of this building upon Christ. For when we really rest upon Him, there comes from the foundation up through all the courses a vital power. Thus Peter puts it: 'To whom, coming as unto a living stone, ye also as living stones are built up.' We might illustrate this by the supposition of some fortress perched upon a rock, and in the heart of the rock a clear fountain, which is guided by some pipe or other into the innermost rooms of the citadel. Thus, builded upon Christ, 'our defence shall be the munitions of rocks, and our waters shall be sure.' From Him, the foundation, there will rise into all the stones, built upon Him, the power of His own endless life, and they, too, become living stones. IV. So note, lastly, the quiet confidence of the builders.
