After accepting Christ as your savior the Bible tells us to associate ourselves with a local New Testament church (Hebrews 10:24-25). A Baptist church is a local assembly of baptized believers who have joined together to carry out Christ's work on earth. When one becomes a church member he is making a covenant with the other members of the church to do his best with God's help to live a Christian life and to cooperate with them to do the church's work.
