By this we mean people who, believing the gospel, have experienced the miracle of new birth, and know themselves to be "children of GOD by faith in our LORD JESUS CHRIST" (Gal. 3:26). We are "not ashamed of the gospel" (Rom. 1:16) and seek to share it with others.
Unconverted people cannot truly participate in worship or other holy activities of the church, nor could they be expected to support its testimony by holy living. CHRISTians are exhorted not to be unequally yoked with unbelievers (2 Cor. 6:14‑18), although we should do good to them and show them by our lives that we belong to the LORD JESUS.
