When we gather as Christians there is a desire to bring glory to the Lord Jesus and to edify the body of Christ. The scriptures says, man cannot live by bread alone but by every word of the mouth of God. When we gather we are listening to what the Lord has to say to His church. The Apostle Paul wrote that God has given some evangelists, and some shepherds and teachers to edify the body of Christ. Each of these offices through the service of the Holy Spirit bring edification to a Christian company.
