I. They would not attend to the dictates of reason. They would not act in the affairs of their souls with the same common prudence with which they acted in other things. Sinners would become saints if they would but show themselves men, and religion would soon rule them if right reason might. Observe it here. Come, and let us reason together, saith the Lord (v. 4, 5): Shall men fall and not arise? If men happen to fall to the ground, to fall into the dirt, will they not get up again as fast as they can? They are not such fools as to lie still when they are down. Shall a man turn aside out of the right way? Yes, the most careful traveller may miss his way; but then, as soon as he is aware of it, will he not return? Yes, certainly he will, with all speed, and will thank him that showed him his mistake. Thus men do in other things. Why then has this people of Jerusalem slidden back by a perpetual backsliding? Why do not they, when they have fallen into sin, hasten to get up again by repentance? Why do not they, when they see they have missed their way, correct their error and reform? No man in his wits will go on in a way that he knows will never bring him to his journey's end; why then has this people slidden back by a perpetual backsliding? See the nature of sin—it is a backsliding it is going back from the right way, not only into a by-path, but into a contrary path, back from the way that leads to life to that which leads to utter destruction. And this backsliding, if almighty grace do not interpose to prevent it, will be a perpetual backsliding. The sinner not only wanders endlessly, but proceeds end-ways towards ruin. The same subtlety of the tempter that brings men to sin holds them fast in it, and they contribute to their own captivity: They hold fast deceit. Sin is a great cheat, and they hold it fast; they love it dearly, and resolve to stick to it, and baffle all the methods God takes to separate between them and their sins. The excuses they make for their sins are deceits, and so are all their hopes of impunity; yet they hold fast these, and will not be undeceived, and therefore they refuse to return. Note, There is some deceit or other which those hold fast that go on wilfully in sinful ways, some lie in their right hand, by which they keep hold of their sins.
