18:11-17 Sinners call it liberty to live at large; whereas for a man to be a slave to his lusts, is the very worst slavery. They forsook God for idols. When men are parched with heat, and meet with cooling, refreshing streams, they use them. In these things men will not leave a certainty for an uncertainty; but Israel left the ancient paths appointed by the Divine law. They walked not in the highway, in which they might travel safely, but in a way in which they must stumble: such was the way of idolatry, and such is the way of iniquity. This made their land desolate, and themselves miserable. Calamities may be borne, if God smile upon us when under them; but if he is displeased, and refuses his help, we are undone. Multitudes forget the Lord and his Christ, and wander from the ancient paths, to walk in ways of their own devising. But what will they do in the day of judgment!
