Matthew 26:16-19 "Now on the first day of Unleavened Bread the disciples came to Jesus and asked, “Where do You want us to prepare for You to eat the Passover?” 18 And He said, “Go into the city to a certain man, and say to him, ‘The Teacher says, “My time is near; I am to keep the Passover at your house with My disciples.”’” 19 The disciples did as Jesus had directed them; and they prepared the Passover."
The disciples grieved over the prospect that one of them could betray Jesus. How often does the Christian exchange their love for Jesus for that momentary indulgence of personal sin? I have found that nothing brings to light my own personal need to confess my sin than when time approaches for the celebration of the Lord's supper (see 1 Corinthians 11:27-32). Thankfully, whenever Jesus had revealed these words, we find Him then blessing the bread and then the fruit of the vine.
Confession of sin ought to be a daily, if not moment-by-moment practice of every Christian. The Lord's table serves to reinforce the provision of God's forgiveness in Jesus Christ. The table of fellowship is predicated upon the restoration of such fellowship that is immediately granted upon confession of sins to the Bishop and Overseer of our souls - the Lord Jesus Christ (see 1 Timothy 2:5; 1 Peter 2:25).
