The important point is that
Jesus was the same yesterday, today and forever.
Jesus created the universe, worked during OT times, came into this world, then came into this world by coming out of woman ( Gal 4:4)
Jesus didn't become a new Jesus, which was mentioned by Calvin as well.
Have you read this Genesis 31:11-13:
The Angel said " I am God at Bethel" v 13, which means
"I am God at the House of God"
Which angel can say so?
But the Angel says again another points:
I am God at Bethel, where you anointedst the pillar, and vowedst a vow unto me.
Here the Angel point out 28:18-20. In other words, the Angel shares everything with God. He says God. There are about 50 places where this Special Angel shows up in OT. The Angel is translated as Angel same as Elohim, but Hebrew Word for it is Malack (The One who is sent)
Jesus emphasized He was sent by Father, as we read in John 9 many times. Siloam means " the one sent" which means Jesus Christ.
Jesus Christ was the true Siloam and the Blind man went to the Siloam and then obtained the sight. We were spiritually blinded but obtained the sight by going to the One who was sent.
Siloam came from " Shalach" to send's passive form.
No human ovum is designed to be combined with Word. By such fertilization did the embryo generate any new brain?
