@Bill -- we're talking about Deity being here to become our Savior.
Obviously that's Your opinion, but it's not based on Scripture.
Jesus Did have earthly half-brothers and a half-sister. But even His half-brother , James did not believe in Him at first. Joseph was Jesus's earthly Father -- no human followers had any relationship with Joseph just because Joseph was His earthly Father.
No one becomes a brother or sister of Jesus Christ through their salvation. We Do become a daughter / son of God Through Jesus Christ by accepting Him / Jesus Christ/ as our personal Savior.
