What does the Bible teach about Jesus?
Biblically, the description of Jesus as the “only begotten” refers to his being the Father’s unique, one-of-a-kind Son for all eternity, with the same divine nature as the Father (see note on John 1:14; cf. John 1:18; 3:16, 18; see also John 5:18; 10:30). Moreover, he is eternal deity (John 1:1; 8:58) and is immutable (Heb. 1:10–12; 13:8), meaning he did not progress to deity but has always been God. And Mary’s conception of Jesus in his humanity was through a miracle of the Holy Spirit (Matt. 1:20).
