WHEN our Lord was going away, He said He would quickly come again; yet knowing that by "quickly" He did not mean what would be at first sight understood by the word, He added, "suddenly," or "as a thief." "Behold I come as a thief; blessed is he that watcheth, and keepeth his garments." [Rev. xvi. 15.] Had His coming been soon, in our sense of the word, it could not well have been sudden. Servants who are bid to wait for their master's return from an entertainment, could not, one should think, be overtaken by that return. It was because to us His coming would not seem soon, that it was sudden. What you expect to come, you wait for; what fails to come, you give up; while, then, Christ said that His coming would be soon, yet by saying it would be sudden, He said that to us it would seem long. 

Yet though to us He seems to delay, yet He has declared that His coming is speedy, He has bid us ever look out for His coming; and His first followers, as the Epistles show us, were ever looking out for it. Surely it is our duty to look out for it, as likely to come immediately, though hitherto for near two thousand years the Church has been looking out in vain.

Is it not something significant that, in the last book of Scripture, which more than any other implies a long continuance to the Christian Church,—that there we should have such express and repeated assurances that Christ's coming would be speedy? Even in the last chapter we are told it three times. "Behold I come quickly; blessed is he that keepeth the sayings of the prophecy of this book." "Behold I come quickly, and My reward is with Me." And again, in the text, "He that testifieth these things, saith, Surely I come quickly." Such is the announcement; and, in consequence, we are commanded to be ever looking out for the great Day, to "wait for His Son from heaven;" [1 Thess. i. 10.] to "look and haste unto the coming of the day of God." [2 Pet. iii. 12.]
