Now, as I have remarked already, and as many of you know, there is a slightly different, twofold form of this phrase in Scripture. I need not trouble you with the minute distinction between the one and the other. Both forms coincide in the important point on which I wish to touch. That representation of believing on Christ carries us away at once from the mere act of acceptance of His word on His authority to the far more manifestly voluntary, moral, and personal act of reliance upon Him. The metaphor is expanded in various ways in Scripture, and instead of offering any thoughts of my own about it, I would simply ask attention to three of the forms in which it is set forth in the Old and in the New Testaments. The first of them, and the one which we may regard as governing the others, is that found in the words of Isaiah, 'Behold, I lay in Zion a stone, a sure Foundation'; and, as the Apostle Peter comments, 'He that believeth on Him shall not be confounded.' There the thoughts presented are the superposition of the building upon its Foundation, the rest of the soul, and the rearing of the life on the basis of Jesus Christ. How much that metaphor says to us about Him as the Foundation, in all the aspects in which we can apply that term! He is the Basis of our hope, the Guarantee of our security, the Foundation-stone of our beliefs, the very Ground on which our whole life reposes, the Source of our tranquillity, the Pledge of our peace. All that I think, feel, desire, wish, and do, ought to be rested upon that dear Lord, and builded on Him by simple faith. By patient persistence of effort rearing up the fabric of my life firmly upon Him, and grafting every stone of it—if I might so use the metaphor—into the bedding-stone, which is Christ, I shall be strong, peaceful, and pure. The storm comes, the waters rise, the winds howl, the hail and the rain 'sweep away the refuge of lies,' and the dwellers in these frail and foundationless houses are hurrying in wild confusion from one peak to another, before the steadily rising tide. But he that builds on that Foundation 'shall not make haste,' as Isaiah has it; shall not need to hurry to shift his quarters before the flood overtake him; shall look out serene upon all the hurtling fury of the wild storm, and the rise of the sullen waters. So, reliance on Christ, and the honest making of Him the Basis, not of our hopes only, but of our thinkings and of our doings, and of our whole being, is the secret of security, and the pledge of peace.
