Why Our Lord Fervently Desired the Last Passover, the First Lord's Supper

The Lord Jesus fervently desired this meal because He was eager for fellowship with us, eager to give Himself to us, eager to secure for us (and assure us of) all of the blessings of the new covenant, and eager to establish for His church the weekly meal of the Lord's Supper in which they might enjoy this fellowship, provision, and security from Him.
