How To Keep the Church Holy (Part 2)
The good news, in short, is that Jesus Christ has won salvation and rule for all who put their trust in him and follow him as Lord. Salvation includes the forgiveness of sins, reconciliation with God in Christ, reconciliation with Christ’s people, and a new Spirit-indwelt heart that now wants to rule obediently for the purposes of representing Jesus on earth.
Jesus has given a kingdom authority to Christians gathered together as a local church that he has not given to individual Christians. Specifically, he has given local churches the authority to exercise the keys of the kingdom through giving and withholding baptism and the Lord’s Supper, thereby doing the work of marking off God’s people from the world.
To define the local church institutionally, then, we could say that it is a group of Christians who regularly gather in Christ’s name to officially affirm and oversee one another’s membership in Jesus Christ and his kingdom through gospel preaching and gospel ordinances.
What then is church membership? It’s a declaration of citizenship in Christ’s kingdom. It’s a passport. It’s an announcement made in the pressroom of Christ’s kingdom. It’s the declaration that a professing individual is an official, licensed, card-carrying, bona fide Jesus representative.
