Charles H. Spurgeon on Psalms 86:9

All nations whom thou hast made, and these include all mankind, since they all come of the first Adam —thy creature, and their lives are all distinct creations of thine omnipotence. All these shall come with penitent hearts, in thine own way, to thine own self, and worship before thee, O Lord. Because thou art thus above all gods, the people who have been so long deceived shall at last discover thy greatness, and shall render thee the worship which is thy due: thou hast created them all, and unto thee shall they all yield homage. This was David's reason for resorting to the Lord in trouble, for he felt that one day all men would acknowledge the Lord to be the only God. It makes us content to be in the minority today, when we are sure that the majority will be with us tomorrow, ay, and that the truth will one day be carried unanimously and heartily. David was not a believer in the theory that the world will grow worse and worse, and that the dispensation will wind up with general darkness, and idolatry. Earth's sun is to go down amid tenfold night if some of our prophetic brethren are to be believed. Not so do we expect, but we look for day when the dwellers in all lands shall learn righteousness, shall trust in the Saviour, shall worship thee alone, O God, and shall glorify thy name. The modern notion has greatly damped the zeal of the church for missions, and the sooner it is shown to be unscriptural the better for the cause of God. It neither consorts with prophecy, honours God, nor inspires the church with ardour. Far hence be it driven.
