1. The generality of them are deaf; they will not hearken to the voice of God's word. He will therefore try his rod, and see who among them will give ear to that, v. 23. We must not despair concerning those who have been long reasoned with in vain; some of them may, at length, give ear and hearken. If one method not take effect, another may, and sinners shall be left inexcusable. Observe, (1.) We may all of us, if we will, hear the voice of God, and we are called and invited to hear it. (2.) It is worth while to enquire who they are that perceive God speaking to them and are willing to hear him. (3.) Of the many that hear the voice of God there are very few that hearken to it or heed it, that hear it with attention and application. (4.) In hearing the word we must have an eye to the time to come. We must hear for hereafter, for what may occur between us and the grave; we must especially hear for eternity. We must hear the word with another world in our eye.
