The Bible tells us that we need to attend church so we can worship God with other believers and be taught His Word for our spiritual growth (Acts 2:42; Hebrews 10:25). Church is the place where believers can love one another (1 John 4:12), encourage one another (Hebrews 3:13), “spur” one another (Hebrews 10:24), serve one another (Galatians 5:13), instruct one another (Romans 15:14), honor one another (Romans 12:10), and be kind and compassionate to one another (Ephesians 4:32).
When a person trusts Jesus Christ for salvation, he or she is made a member of the Body of Christ (1 Corinthians 12:27). For a church body to function properly, all of its "body parts" need to be present (1 Corinthians 12:14-20). Likewise, a believer will never reach full spiritual maturity without the assistance and encouragement of other believers (1 Corinthians 12:21-26). For these reasons, church attendance, participation, and fellowship should be regular aspects of a believer's life. Someone who has trusted Christ should have a desire to worship God, be taught His Word, and fellowship with other believers.
