“I am told that years ago a boat was upset above the falls of Niagara, and two men were being carried down the current, when persons on the shore managed to float a rope out to them, which rope was seized by them both.
One of them held fast to it and was safely drawn to the bank; but the other, seeing a great log come floating by, unwisely let go the rope and clung to the log, for it was the bigger thing of the two, and apparently better to cling to. Alas! the log with the man on it went right over the vast abyss, because there was no union between the log and the shore.
The size of the log was no benefit to him who grasped it; it needed a connection with the shore to produce safety. So when a man trusts to his works, or to sacraments, or to anything of that sort, he will not be saved, because there is no junction between him and Christ; but faith, though it may seem to be like a slender cord, is in the hands of the great God on the shore side; infinite power pulls in the connecting line, and thus draws the man from destruction. Oh the blessedness of faith, because it unites us to God!”
