Phil 2:
5In your relationships with one another, have the same mindset as Christ Jesus:
6Who,
being in very nature <a href="https://biblehub.com/niv/philippians/2.htm#footnotes" title="Or in the form of">a</a> God,
did not consider equality with God something to be used to his own advantage;
7rather, he made himself nothing
by taking the very nature <a href="
https://biblehub.com/niv/philippians/2.htm#footnotes" title="Or the form">b</a> of a servant,
being made in human likeness.
8And being found in appearance as a man,
he humbled himself
by becoming obedient to death—
even death on a cross!
9Therefore God exalted him to the highest place
and gave him the name that is above every name,
10that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
11and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
Jesus was God before he took on flesh. God can do anything, including taking on flesh and remaining God. Nothing is impossible with God.
