…for Thou wast slain, and hast redeemed us to God by Thy blood out of every kindred, and tongue, and people, and nation… – Revelation 5:9

What are we going to be, brothers and sisters, we who are in Christ? We have not any idea of what holiness, and glory, and bliss, shall yet be ours. “It doth not yet appear what we shall be.” We may rise even while on earth to great heights of holiness, -and the higher the better; but there is something better for us than mortal eye has ever seen, or mortal ear has ever heard. There is more grace to be in the saints than we have ever seen in them, the saintliest saint on earth was never such a saint as they are yonder who are before the throne of the Most High; and I know not but that, even when they get there, there shall be a something yet beyond for them, and that through the eternal ages they shall still take for their motto, “Onward and upward!” In heaven, there will be no “Finis.” We shall still continue to develop, and to become something more than we have ever been before; not fuller, but yet capable of holding more, ever growing in the possibility of reflecting Christ, and being filled with His love; and all the while our Lord Jesus Christ will be charmed and delighted with us. As He hears our lofty songs of praise, as He sees the bliss which will ever be flashing from each one of us, as He perceives the divine ecstasy which shall be ours for ever, He will take supreme delight in it all. “My redeemed,” He will say, “the sheep of My pasture, the purchase of My blood, borne on My shoulders, My very heart pierced for them; oh! how I delight to see them in the heavenly fold! These, My redeemed people, are joint heirs with Me in the boundless heritage that shall be theirs for ever; oh, how I do delight in them!” ~ C.H. Spurgeon
