Isaiah 7:14 "Therefore the Lord Himself will give you a sign: Behold, a virgin will be with child and bear a son, and she will call His name Immanuel."
By implication, Jesus' virgin birth qualified him in His humanity to be our Savior. Salvation would had been of no effect were it not for the virgin birth. All who respond by faith to the Spirit's quickening work of regeneration in their souls have a miraculous new birth (John 3:3-6; James 1:18; 1 Peter 1:23) which enables the Christian to say they have had a miraculous new birth based upon the One who in His humanity had virgin birth had a miraculous birth. Thanks be to God that Jesus, God in human flesh, was virgin born with reagrds to His humanity. He is qualified and is the sinless Savior and scripture is the inerrant, infallible Word of God. Its that important!
