How can an eternal, who is not bound by time, be incarnated?

The incarnation presents an insuperable barrier to divine timelessness. Christ is clearly not timeless in that be became in time what he was not in eternity, and this “new” divine manifestation continues permanently into an interminable, temporal future. Further, if timelessness can be predicated of God, then Christ is being eternally humiliated and killed in a timeless “now,” which is unconscionable (see, e.g., Acts 13:33; Phil 2:5–11, etc.).

This is the most difficult tension for the idea of divine atemporality, but it is not a hopeless one. In keeping with the answer immediately above, we offer here that there was no point of “time” in which the second person of the Trinity was unconscious of idea of incarnation or unwilling to take on humanity. Further, it is important to note that God did not technically become a man, but rather took on humanity, incurring no essential change in his self. As such, the action of incarnation presents no more difficulty than any other divine action.
