There are three dimensions of time in this verse:
First of all, there is the past: “The Lord’s death.”
Secondly, there is the present: “As often as ye eat..and drink…ye show the Lord’s death.”
Thirdly, there is the future: “Till He come.”
As we sit down and enjoy the Lord’s presence at the Lord’s table today, may we look back to the past with grateful thanksgiving and praise; on to the future with joyful anticipation; and in it all, worship Him now, remembering the words of the Lord Jesus, when He said to the woman at the well, “The hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship Him” (John 4:23).
