All Christians are responsible before God to take themselves in hand, deny themselves, take up their cross, and follow Jesus. To do so requires that we daily bring our bodies, minds, and wills in subjection to the lordship of Jesus Christ. But it is fundamentally important to understand that we do not live the Christian life in isolation. If we are isolated from other Christians in meaningful, Spirit-filled community, we are not living the Christian life, regardless of our protestations to the contrary. And, like the individual Christian, the corporate body is responsible to discipline itself before God for godliness.
The Lord’s Supper pictures and presents the gospel to us: to our sight, our touch, our taste. In the Lord’s Supper we commune with Christ and therefore with his people. When we eat the bread and drink the cup, we reaffirm our trust in Christ and our commitment to his people. When we celebrate the Lord’s Supper, we embrace Christ all over again, and we also embrace all who are his.
