(1.) It is very rich, v. 4. Men have not heard nor seen what God has prepared for those that wait for him. Observe the character of God's people; they are such as wait for him in the way of duty, wait for the salvation he has promised and designed for them. Observe where the happiness of this people is bound up; it is what God has prepared for them, what he has designed for them in his counsel and is in his providence and grace preparing for them and preparing them for, what he has done or will do, so it may be read. Some of the Jewish doctors have understood this of the blessings reserved for the days of the Messiah, and to them the apostle applies these words; and others extend them to the glories of the world to come. It is all that goodness which God has laid up for those that fear him, and wrought for those that trust in him, Ps. xxxi. 19. Of this it is here said that since the beginning of the world, in the most prying and inquisitive ages of it, men have not, either by hearing or seeing, the two learning senses, come to the full knowledge of it. None have seen, nor heard, nor can understand, but God himself, what the provision is that is made for the present and future felicity of holy souls. For, [1.] Much of it was concealed in former ages; they knew it not, because the unsearchable riches of Christ were hidden in God, were hidden from the wise and prudent; but in latter ages they were revealed by the gospel; so the apostle applies this (1 Cor. ii. 9), for it follows (v. 10), But God has revealed them unto us by his Spirit; compare Rom. xvi. 25, 26, with Eph. iii. 9. That which men had not heard since the beginning of the world they should hear before the end of it, and at the end of it should see, when the veil shall be rent to introduce the glory that is yet to be revealed. God himself knew what he had in store for believers, but none knew besides him. [2.] It cannot be fully comprehended by the human understanding, no, not when it is revealed; it is spiritual, and refined from those ideas which our minds are most apt to receive in this world of sense; it is very great, and will far outdo the utmost of our expectations. Even the present peace of believers, much more their future bliss, is such as surpasses all conception and expression, Phil. iv. 7. None can comprehend it but God himself, whose understanding is infinite. Some give another reading of these words, referring the transcendency, not so much to the work itself as to the author of it: Neither has the eye seen a god besides thee, who doth so (or has done or can do so) for him that waits for him. We must infer from God's works of wonderous grace, as well as from his works of wondrous power, from the kind things, as well as from the great things, he does, that there is no god like him, nor any among the sons of the mighty to be compared with him.
