Behold, He is coming with clouds, and every eye will see Him, even they who pierced Him. And all the tribes of the earth will mourn because of Him. Even so, Amen. – Revelation 1:7

Brothers and Sisters, do not your souls take fire as you think of the praises of Immanuel? Gladly would I fill the universe with His praise! Oh! for a thousand tongues to sing the glories of the Lord Jesus!

“Behold, He comes with clouds!” (John’s) adoration awoke his expectation, which all the while was lying in his soul as an element of that vehement heat of reverent love which he poured forth in his doxology. “Behold, He comes,” he said, and thus he revealed one source of his reverence. “Behold, He comes,” he said, and this exclamation was the result of his reverence… “Behold, He comes,” or is coming—he means to assert that He is even now on His way! As workmen are moved to be more diligent in service when they hear their master’s steps, so, doubtless, saints are quickened in their devotion when they are conscious that He whom they worship is drawing near. He has gone away to the Father for a while and so He has left us alone in this world—but He has said, “I will come again and receive you unto Myself”—and we are confident that He will keep His word! Sweet is the remembrance of that loving promise. That assurance is pouring its savor into John’s heart while he is adoring and it becomes inevitable, as well as most meet and proper, that his doxology should, at its close, introduce him to the Lord, Himself, and cause him to cry out, “Behold, He comes!” Having worshipped among the pure in heart, he sees the Lord. Having adored the King, he sees Him assume the Judgement Seat and appear in the clouds of Heaven! When once we enter upon heavenly things, we know not how far we can go, nor how high we can climb! John, who began with blessing the Churches, now beholds His Lord! ~ C.H. Spurgeon
