Why should Christians observe the Lord's table instead of Old Testament feasts?

The observance of the Lord's table is central to Christian faith as it commemorates the death of Christ, the ultimate Passover lamb. Unlike the Old Testament feasts, which were shadows of things to come, the Lord's Supper is a tangible expression of the new covenant established by Christ's blood. In the Lord's table, we are called to remember not only the act of Christ's sacrifice but also the covenant of grace that we are under. This observance reminds believers that our righteousness and sanctification are found in Him alone, rejecting any notion of relying on the works of the law. Instead, we gather to partake in this feast with faith and gratitude for what Christ has accomplished for us.
