Hope and purity go together. Those who long for Jesus to come, also long for purity in heart and in the world. Partaking of this supper is an expression of both. We are proclaiming the Lord’s death until He comes again. When we eat and drink weekly here, we are saying the Savior sustains us until His second advent. We long to see Him, for we will be like Him.
And one thing Jesus is that we are not, is pure. We long for this. And Jesus is taking us there. our union with Him is the main way He does it, by the Spirit. And that is what is happening here in a special way. It isn’t called communion for nothing. Here you have a unique communication, a special union with Christ.
