Because of Jesus's virgin birth, and the absence of intercourse between Mary and Joseph, what was Jesus's DNA? Something perfectly made to house the pre-existent Son of God. Some people believe that Jesus was not a divine preexistent being. Jesus tells us that He came from the Father and was there when all was made. In addition to this, a compelling account is given by Paul.
Phillipians 2:6-7
Who, though he was in the form of God, did not regard equality with God something to be grasped.
Rather, he emptied himself, taking the form of a slave, coming in human likeness; and found human in appearance,
Scripture states very plainly that Jesus was a preexistent being who came to earth in human likeness. He as the Christ is not a man, He prexisted men and Adam. He was there when all was made.
So if Jesus is not a human and is a prexistent being, who is He?
An important account is given in Hebrews:
Hebrews 1:1-4
1 In times past, God spoke in partial and various ways to our ancestors through the prophets;
2 in these last days, he spoke to us through a son, whom he made heir of all things and through whom he created the universe,
3 who is the refulgence of his glory, the very imprint of his being, and who sustains all things by his mighty word. When he had accomplished purification from sins, he took his seat at the right hand of the Majesty on high,
4 as far superior to the angels as the name he has inherited is more excellent than theirs.
Jesus is not an angel, but is much higher than them.
Jesus is the very imprint of the Father's being. A truly intimate relationship exists between the Father and Son.
Hebrews 1:6-7
6 And again, when he leads the first-born into the world, he says: "Let all the angels of God worship him."
7 Of the angels he says: "He makes his angels winds and his ministers a fiery flame";
8 but of the Son: "Your throne, O God, stands forever and ever; and a righteous scepter is the scepter of your kingdom.
The Son is regarded, not only equal to God, but as God.
I fail to understand why a number of people fail to accept Jesus Christ as a pre-existent being, and as God. As the Nicene Creed summarizes Christ's nature as "One in being with the Father, through Him all things were made".
