When I started for California I procured a guide-book. This told me, that after leaving the State of Illinois, I should cross the Mississippi, and then the Missouri; get into Nebraska; then over the Rocky Mountains to the Mormon settlement at Salt Lake City, and by the way of the Sierra Nevada into San Francisco. I found the guide book all right as I went along; and I should have been a miserable sceptic if, having proved it to be correct three-fourths of the way, I had said that I would not believe it for the remainder of the journey. Suppose a man, in directing me to the Post Office, gives me ten landmarks; and that, in my progress there, I find nine of them to be as he told me; I should have good reason to believe that I was coming to the Post Office. And if, by believing, I get a new life, and a hope, a peace, a joy, and a rest to my soul, that I never had before; if I get self-control, and find that I have a power to resist evil and to do good, I have pretty good proof that I am in the right road to the "city which hath foundations, whose builder and maker is God." And if things have taken place, and are now taking place, as recorded in God's Word, I have good reason to conclude that what yet remains will be fulfilled. And yet people talk of doubting. There can be no true faith where there is fear. Faith is to take God at His word, unconditionally. There cannot be true peace where there is fear. "Perfect love casteth out fear." How wretched a wife would be if she doubted her husband! and how miserable a mother would feel if after her boy had gone away from home she had reason, from his neglect, to question that son's devotion! True love never has a doubt. There are three things indispensable to faith--knowledge, assent, and appropriation. We must know God. "And this is life eternal, that they might _know_ Thee, the only true God, and Jesus Christ whom Thou hast sent" (John xvii. 3). Then we must not only give our assent to what we know; but we must lay hold of the truth. If a man simply give his assent to the plan of salvation, it will not save him: he must accept Christ as his Saviour. He must receive and appropriate Him. Some say they cannot tell how a man's life can be affected by his belief. But let some one cry out that some building in which we happen to be sitting, is on fire; and see how soon we should act on our belief and get out. We are all the time influenced by what we believe. We cannot help it. And let a man believe the record that God has given of Christ, and it will very quickly affect his whole life. Take John v. 24. There is enough truth in that one verse for every soul to rest upon for salvation. It does not admit the shadow of a doubt. "Verily, verily"--which means truly, truly--"I say unto you, He that heareth My word, and believeth on Him that sent Me, hath--_hath_--everlasting life, and shall not come into condemnation; but is passed from death unto life."
