New Defender's Study Bible Notes
4:10 Saviour. Jesus Christ, of course, is the Savior; also God is the Savior. This is further incidental proof that Jesus Christ is God. See also Titus 3:4.
4:10 all men. Christ’s death is sufficient to save all men (I John 2:2), but it becomes effective only for those who believe (John 3:36).
