And there I will meet with thee, and I will speak with thee from above the ark-cover, from between the two cherubim which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel. Exodus 25:22| LSG
Preaching the gospel is the primary mission of the church because the church is God's agency to evangelize the world. Jesus compared the church to a householder who went out into the marketplace to hire laborers into his vineyard, Matthew 20:1-16. Jesus also compared the nature of the kingdom of heaven to a sower who went forth to sow. The seed the sower was sowing was the word of God, Matthew 13:3-23. In time of the Apostles, the church was God's agency to send preachers out to preach the word and do the work of God. The Bible says of the church at Antioch, "And when they had fasted and prayed and laid their hands on them, they sent them away" (Acts 13:1-3). The apostle Paul said in 1 Timothy 3:15 that the church is the pillar and ground of the truth. A pillar is a large stone that supports the roof of a porch or a building. The church supports and upholds the truth of God. The apostle Paul also identified the church as the institution, which is to make known the wisdom of God. Ephesians 3: 10, "To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God." I understand therefore that the church is to be employed in the dissemination of the wisdom of God. Paul further said: "To him be glory in the church and in Christ Jesus throughout all generations, for ever and ever" (Ephesians 3:21). It is God's will that His glory be in the church through Christ Jesus. Matthew stressed that the great commission is the center of the church. He recorded Jesus saying: "All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world" (Matthew 28:18-20)
