I’d like to hear some apologetic approaches to the following argument:
If God does not change (Mal 3:6), and Jesus Christ is the same yesterday, today, and forever (Heb 13:8), then that means God never changes in Who He is. Therefore, the Incarnation (an therefore, the Conception in Mary’s womb) is an impossibility. Jesus grew (which is a change), and furthermore, the Incarnation denotes a moment in time when God took on humanity (which is a change). Since the human being Jesus has not always existed (if he was truly conceived and born), then the Word of God, the Son of God, the second Person of the Trinity, has not always been the human being Jesus.
I have my own line of reasoning to combat the argument, but I’d like to hear other approaches (especially since I don’t have a “background” in apologetics).
