1. Evangelism: Mankind is lost in sin (Rom. 3:23) and the gospel is the only power to save (Rom. 1:16) therefore God wants the only gospel preached, and has given the obligation to preach the gospel of Jesus Christ to the church only. (Matt. 28:18-20; Mk. 16:15; 1 Cor. 1:21)
   
2. Edification: The churches spiritual strength comes by edification (Eph. 4:16) and such insures that the church is grounded and stabilized, which prevents false doctrine from leading it astray (Col. 2:6-7). Paul wrote: "Let all things be done for edification." (1 Cor. 14:26). The church must develop itself to so that its members can teach others (Heb. 5:12), and resist the Devil in all of his devices (Jas. 4:7; 1 Pet. 5: 9; 2 Cor. 2:11).
   
3. Benevolence: God says we are to take care of our own, and not burden the church, so that the church can relieve those saints who have no one to care for them (1Tim. 5:16). If we do not provide for our own, we are worse than an infidel (1 Tim. 5:8). One example is the church at Jerusalem which relieved the needs of its destitute members who remained in Jerusalem after their conversion to the Lord (Acts 2:44-45; 4:32-35)

“I do not pray for these alone, but also for those who will believe in Me through their word; 21 that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.”  (John 17:19-21)

These words which were penned by the inspiration of God leave no doubt that in the Lord's church which He purchased with His blood, must be unified, not divided (Acts 20:28; Matt. 16:18). Paul wrote: , “let there be no divisions among you” (1Cor 1:10), and therefore as disciples of Christ Jesus we seek to be united in the one spirit through the written word so that all who are in the world may, by seeing our united faith, believe that Jesus is the Son of God, sent by God to build the one church by one Spirit and one faith (Eph. 4:1-5). We are members of Christ’s everlasting church which was established on the day of Pentecost and we live to serve Him. He is the only Head of the church which is His body (Acts 2; Col. 1:24). We are not part of any denomination of which all have been established after Pentecost, and have different heads / founders other than Chirst. Search your Bible, look for another church named after someone other than Christ. You won't find one!
As Christians only, it is our aim to do the work God intended the church to do without addition or subtraction. The church is the pillar and ground of the truth (1Tim. 3:15) and its work is divine, great and glorious because the church is divine, great and glorious. Therefore, as blessed children we focus on the three works as ascribed in the Bible the pattern for the church.
