(II Timothy 4:3) But rather (vs15) the increased comprehension of the Love of Christ by the Spirit (3:18-19) manifests itself in a "speaking the truth in love, growing up in all things INTO HIM WHO IS THE HEAD--CHRIST, and it is from our Head, Christ Jesus, Vs 16 "that the whole body is joined and knit together by what every joint supplies , according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love."
Did you notice, it's all about Christ! The Father's purpose has been accomplished in Christ before the foundation of the world and in history, on the cross. He manifests the wisdom of His Will and Purpose in the church before the angels and everybody, by conforming His people to the image of Christ Who is the exact image of God (Hebrews 1:3), the fulness of the Godhead in human flesh!(Colossians 2:9 If church leadership is not equipping the saints to show forth the sacrificial love of Christ to one another, strengthening the feeble knees and lifting up the hands that hang down, then they are about some other business than God's.
But what about evangelism?, you say. In John 17, our Lord's prayer to the Father for His people, vs 21 He prays for all those who will believe in Him because of the Apostolic witness, and He says, "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." And again in vs 22, in words reminiscent of Paul's Ephesian exhortation, "I in them, and You in Me, that they may be perfect in one, and THAT THE WORLD MAY KNOW THAT YOU HAVE SENT ME, AND HAVE LOVED THEM AS YOU HAVE LOVED ME." That is Jesus' method of evangelism, the very work of the ministry in Ephesians 4 that unites His people in the One of the Godhead, that the world may know that the Father sent the Son! No amount of money, no high powered methodology, no amount of "hell fire preaching" can replace our Lord's Gospel Method. People who are growing up in the Love of God and manifest a heavenly devotion to one another because they think and operate like their Head--this becomes the spectacle presented before the world that the world may know that the Father sent His Son for the sins of His people. This is God's witness to the fulfilling of His Will in gathering together in One all things in Christ (Ephesians 1:10), and that to a world that only knows wars and rumors of wars. The book of Acts is the foundational activity of this method. Read it and behold the Work of the Holy Spirit of God in "adding to the church daily those who were being saved." (Acts 2:47)
