For as often as you eat this bread and drink this cup, you proclaim the Lord’s death till He comes. – 1 Corinthians 11:26

At the Lord’s Supper, there is no discerning the Lord’s body unless you discern His First Coming—but there is no drinking of His cup to its fullness, unless you hear Him say, “Until I come.” You must look forward as well as backward! So must it be with all our ministries—they must look to Him on the Cross and on the Throne. We must vividly realize that He, who has once come, is coming again, or else our testimony will be marred and one‐sided. We shall make lame work of preaching and teaching if we leave out either advent.

And next, it is to be unquestionably asserted. “Behold, He comes!” It is not, “Perhaps He will come,” nor “Perhaps He may yet appear.” “Behold, He comes,” should be dogmatically asserted as an absolute certainty which has been realized by the heart of the man who proclaims it. “Behold, He comes!” All the Prophets say that He will come. From Enoch down to the last that spoke by Inspiration, they declare, “The Lord comes with ten thousands of His saints.” You shall not find one who has spoken by the authority of God who does not, either directly or by implication, assert the coming of the Son of Man when the multitudes born of woman shall be summoned to His bar to receive the recompense of their deeds! All the promises are travailing with this prognostication, “Behold, He comes!” We have His own word for it, and this makes assurance doubly sure. He has told us that He will come again. He often assured His disciples that if He went away from them, He would come again to them—and He left us the Lord’s Supper as a parting token to be observed until He comes. As often as we break bread, we are reminded of the fact that though it is a most blessed ordinance, yet it is a temporary one and will cease to be celebrated when our absent Lord is once again present with us! ~ C.H. Spurgeon
