Jesus calls us to learn from teachers and follow the example of godly leaders (Hebrews 13:7). Members gather, encourage, and grow with one another under the leadership of the church.
Jesus calls us to the life of the local church (Hebrews 10:25). Membership gives you a greater opportunity to participate in and shape the ministry of the church.
Jesus calls us to unity within a body of believers (1 Corinthians 1:10). Members are united together for the sake of the Gospel.
