I. Look at true foundations. (1) God is God, before all things pre-ordaining, revolving within Himself and all things else, as He pleases, the great foundation given to Moses in the bush "I am!" (2) This good God has given us a revelation. We can prove it by every evidence: the externalevidence prophecy; the internalevidence the harmony; the experimentalevidence what it has been to many, and what it is to me. (3) In the revelation there is shown a way the only way by which a just God can forgive a sinner. He has found and accepted a Substitute, Who outweighs the whole world His own Son. (4) To communicate this thought and to give this faith, there is a Holy Ghost, Himself also God; and He being spirit, works in the spirit of a man, and creates in his heart trust and love towards Jesus Christ. (5) As soon as by that Spirit a man really trusts, as a sinner, in Christ, he is united to Christ. God sees him in Christ, and in Christ God sees him righteous. (6) By the same union, and through the operation of the Holy Ghost, that man, now a living member in Christ, has a motive sufficient to change his whole life and to make him do all good works. God, inspiration, Christ, the Holy Ghost, faith, good works these are the foundations.
II. Be always looking to foundations and resting in foundations. Sometimes a child of God thinks he has lost his foundations. (1) If he thinks so, he should see whether any part of his foundation is impaired, or loose, or out of order. (2) If he finds out the fault, he should try to repair it; but if not, then let him throw himself back at once on the all foundation that God is God. There is nothing in the world so sure as a believer's foundation. As the whirlwind passeth, so is the wicked no more, but the righteous is an everlasting foundation.
