God has made the church responsible for holding forth the truth of the gospel to the world. The church at Thessalonica was commended for the diligent way in which they undertook this mission; "...so that you became an example to all the believers in Macedonia and Achaia. For the word of the Lord has sounded forth from you, not only in Macedonia and Achaia, but also in every place your faith toward God has gone forth, so that we have no need to say anything." (I THESSALONIANS 1:7,8).
Some in the local church at Corinth were having a difficult time cooperating with one another. They were still too carnal; envious and jealous of one another. Paul told them that their relationship to Jesus and to one another, and the heavy responsibility of the work God had given them to do, made it important for them to put away such worldly attitudes. He described the local church as a body which needs the efforts of every one of its members: "...Now you are Christ's body, and individually members of it." (I CORINTHIANS 12:14-27).
The local church today needs each of its members to join in the godly efforts of the congregation. "The body is not one member, but many." If each member does not do His part, then the most important work we could possibly be involved with suffers. The church is the body of Christ; and He is the head of the body. We must listen to the head. Because of the human part, no local church is perfect. But because of Christ, let each member push on toward perfection, always growing, and never quitting.
