The church is doing life together with other Christians in a way that reflects the love of God to a watching world.
In biblical community, we are to encourage each other, meet together, hold each other accountable, pray for each other, care for each other, speak life into each other, study God's Word together, and grow in faith together. The Apostle Paul wrote most of the New Testament. His writings consisted of letters to different churches during various times of their growth. In short, his letters were instructions on how to live and grow towards each other!
