…for the LORD hath redeemed Jacob, and glorified Himself in Israel. – Isaiah 44:23

The Lord might have created myriads more of pure spirits like the angels, but He desired to be served and loved by beings who should be in part material, and yet should be akin to Himself: beings who should possess freedom of will and should know both good and evil, and yet should for ever choose good alone. Behold how such creatures have been produced! Not so much by creation as by redemption. The glorified ones once plunged deep into sin, but they were, without a violation of their free agency, recovered to their allegiance by the love of Jesus, and then lifted up into such a position that in Christ Jesus they are akin to God Himself, so that no order of beings intervenes between them and God; and yet they never will nor can presume, nor take ambitious advantage of their elevated position. If God were to create free agents, knowing both good and evil, and put them where men will be in heaven, without their undergoing any preparatory process, it would be a dangerous experiment; but for Him to let them know evil to the full, and yet be for ever bound to perfect holiness, because infinite love sways them with omnipotent obligations of gratitude,-this is to make creatures which bring exceeding glory to their Author. These are not merely fashioned on His wheel but dipped into the blood of His own suffering and indwelt by His own mighty power, and well may they be precious in His sight. “Glory, glory, how the angels sing”; but far louder are the notes of the redeemed. “Glory, glory,” thrice and sevenfold told is that which comes from those loud harps of ransomed ones, who have washed their robes and made them white in the blood of the Lamb. The Lord hath glorified Himself in Israel. ~ C.H. Spurgeon
