He who testifies to these things says, “Surely I am coming quickly.” Amen. Even so, come, Lord Jesus! – Revelation 22:20

There is this sense lying in the background—that (Jesus) is already on the way. All that He is doing in Providence and Grace is a preparation for His coming. All the events of human history; all the great decisions of His august majesty whereby He rules all things—all these are tending towards the day of His appearing! Do not think that He delays His coming and then, all of a sudden, He will rush here in hot haste. He has arranged for it to take place as soon as Wisdom allows. We know not what may make the present delay imperative, but the Lord knows and that suffices. You grow uneasy because nearly 2,000 years have passed since His Ascension and Jesus has not yet come. But you do not know what had to be arranged and how far the lapse of time was absolutely necessary for the Lord’s designs. Those are no little matters which have filled up the great pause—the intervening centuries have teemed with wonders! A thousand things may have been necessary in Heaven, itself, before the consummation of all things could be arrived at.

When our Lord comes, it shall be seen that He came as quickly as He could, speaking after the manner of His Infinite Wisdom for He cannot behave Himself otherwise than wisely, perfectly, divinely. He cannot be moved by fear or passion so as to act hastily as you and I too often do. He dwells in the leisure of eternity and in the serenity of Omnipotence. He has not to measure out days, months and years—or to accomplish so much in such a space or else leave His lifework undone. But according to the power of an endless life, He proceeds steadily on and to Him a thousand years are but as one day! Therefore be assured that the Lord is even now coming! He is making everything tend that way. All things are working towards that grand climax. At this moment and every moment since He went away, the Lord Jesus has been coming back. “Behold, He comes!” He is on the way! He is nearer every hour! ~ C.H. Spurgeon
