In our celebration of the Lord's Supper, our primary focus is on what Jesus Christ, our Saviour,has done for us. This is the "there and then" part of the Lord's Supper. We remember His death for us. We think of Him. We give thanks to Him.
There is also a secondary focus of attention. It's the "here and now" part of the Lord's Supper: our response to Him. We are not only remembering the story of what happened a long time ago. As well as remembering Him - what He did for us there and then, we are responding to Him here and now.
May God bless each of us in both our remembering Him and our responding to Him.
