Circle the Wagons!
One of the very obvious characteristics of the first-century church was the fellowship of believers. They were drawn to each other primarily because of their new life in Christ. They continued together, growing steadfast in doctrine, in the Lord's Supper, and in praying together. Furthermore, they met one another's physical needs. That was a witness of their changed life and the strengthening of their faith for witnessing. Their obedience to the Word in fellowship produced much fruit, giving them favor with those who saw their changed lives, and the Lord added new believers to the church daily (Acts:2:42-47).
If we are not experiencing fellowship with other believers, besides being disobedient to the Word, we are missing out on what God has provided for our growth, encouragement, edification, consolation, and spiritual welfare and protection. All of this is especially critical as apostasy increases and the world steps up its attacks against Christ and His followers.
