11 This Epistle and 2 Thessalonians were addressed to the local church in Thessalonica, composed of all the believers in Christ in that city. Such a local church is of the believers and is in God the Father and the Lord Jesus Christ. This indicates that a local church is born of God the Father with His life and nature and is united with the Lord Jesus Christ organically in all that He is and has done. Hence, it is of men (such as the Thessalonians), yet is in God and in the Lord organically. This organic union in the divine life and nature is the vital base for the believers to live a holy life for the church life. Such a living is the theme of the two Epistles.
