Nope incarnation isn't something in the bible.
Sorry, but there's quite a few text references to that effect.
Gospel of John aside, and the implicit elements in the Synoptics, we have Paul
Philippians 2:7-8
"Let the same mind be in you that was in Christ Jesus, who, though he was in the form of God, did not regard equality with God as something to be exploited, but emptied himself, taking the form of a slave, being born in human likeness. And being found in human form, 8 he humbled himself and became obedient to the point of death— even death on a cross."
Here there are four phrases that express incarnation – emptied himself, taking the form of a slave, being born in human likeness, being found in human form.
2 Corinthians 8:9:
For you know the generous act of our Lord Jesus Christ, that though he was rich, yet for your sakes he became poor, so that by his poverty you might become rich.
Romans 8:3-4
For God has done what the law, weakened by the flesh, could not do: by sending his own Son in the likeness of sinful flesh, and to deal with sin, he condemned sin in the flesh, so that the just requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.
Galatians 4:4-6
But when the fullness of time had come, God sent his Son, born of a woman, born under the law, in order to redeem those who were under the law, so that we might receive adoption as children. And because you are children, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!”
For Paul:
1. Incarnation and cross are inseparable.
2. Both incarnation and cross are necessary for our salvation.
3. Both incarnation and cross express the self-giving love of God in Christ.
4. Both incarnation and cross should narratively shape the Christian believer and community into the image of Christ, decisively affecting Christian praxis in multiple ways and in all areas of life.
5. A Pauline theology/spirituality of theosis (becoming like God, in Christ, by the Spirit) is able to hold incarnation and cross together. And with that link, incarnation, cross, and resurrection/exaltation are all tied together in Paul.
