The bringing forth here is the begetting in Acts 13:33. The incarnated Christ, including all His believers, was begotten in His resurrection to be the Son of God (1 Pet. 1:3). Thus, He has become the firstborn Son of God, and all His believers have become God's many sons as His brothers to constitute His church (Rom. 8:29; John 20:17 and note John 20:172a; Heb. 2:10-12) as His multiplication (John 12:24), His increase (John 3:29-30), and His Body, which is His fullness, His expression (Eph. 1:23).
