Our Father God is a spirit not seen with visible eyes, and from the beginning, Jesus also was in spirit form.
Jesus was Spirit not flesh until the Holy Spirit placed the seed containing Jesus into the womb of Mary. At that precise moment Jesus because human flesh, however his blood was divine and of his Father God. Scientist tell us the baby's blood is not from the mother but from the father. This fact reveals that the blood of Jesus was sinless, holy and pure and from God himself. This fact alone is the reason that the blood that Jesus shed on the cross is able to wash away our sins.
As we take a quick look at the gospel of John chapter one we see "In the beginning was the WORD and the WORD was with God and the Word was God. As we continue reading we discover that John was speaking of Jesus the WORD and also saying Jesus was God and was working in tandem with the Father creating the world.
We take a look at the first book in the Bible; Genesis chapter 1, and we view that the Spirit of God hovered over the waters. Each time our Father God spoke WORDS - - a portion of earth was formed. Light was split from darkness, Waters were divided from the sky, the sun, moon and stars came into being, trees and vegetation came, and creatures of all types of animals were created. Jesus was there in the beginning with His Father God.
God could not allow them to stay in their fallen state, and eat of the Tree of Life, so it was necessary that they be removed from the garden and now mankind must toil and work for a living. God slew a lamb as a sacrifice and made garments to cover Adam and Eve's nakedness. This was the first blood sacrifice.
God gave Adam and Eve a promise that he would send a redeemer and many Prophets in the Old Testament told how a virgin would bring forth a savior, who would be born in
Prophesy of Micah 5:2 "But you, Bethlehem Ephrathah, though you are small among the clans of Judah, out of you will come for me one who will be ruler over Israel, whose origins are from of old, from ancient times."
(Fulfillment of the Prophesy) Matthew 2:1-6 After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem and asked, "Where is the one who has been born king of the Jews? We saw his star when it rose and have come to worship him." 3 When King Herod heard this he was disturbed, and all Jerusalem with him. 4 When he had called together all the people's chief priests and teachers of the law, he asked them where the Messiah was to be born. 5 "In Bethlehem in Judea," they replied, "for this is what the prophet has written: 6" 'But you, Bethlehem, in the land of Judah, are by no means least among the rulers of Judah; for out of you will come a ruler who will shepherd my people Israel.'"
Isaiah the prophet in chapter 53 revealed how the Savior would suffer and die for the world, and that by his stripes we would be healed.
