John 14:10-11 Believest thou not that I am in the Father, and the Father in me?
Does John (14:10-11) Indicate Incarnation?
(John 14:10-11) does NOT indicate incarnation but unification. This passage denotes two spirits (“I am in the Father” or “the Father in Me”) agreeing as one (on one accord).
When used in the sense of “in God,” or “in Christ,” the word “in” refers to a close communion, a tight fellowship. This manner of speaking was part of the language usage of that day, (John 10:37-38, 17:21, 23, 26) (See also: In, In God, In Whom)
(2 Corinthians 5:17) – Therefore if any man be “in” Christ, he is a new creature: old things are passed away; behold, all things are become new. Yet we all know that this verse is not literal; man is not literally inside another individual, this is figuratively spoken. Man is also not a new physical being but a changed spiritual being. Man’s old way of thinking, living and behaving die (but not literally, they change) and his thoughts, actions, and life become new (different).
In the same way, when Jesus Christ submitted his human will to God, God’s will was then “in” him; Jesus laid aside his human will in order to be united to God’s perfect will. “Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.” (Luke 22:42)
The spirit of God was in Christ in the same way God’s spirit is in those who serve him today. Having the “in”-dwelling of God’s spirit does not make us God/gods.
When we are doing God’s will, following his leading we are “one” with God. Thus we, I and my father (spiritually), are indeed one (unified). We are also one with Christ (you and I).
Note: The Bible is full of figurtive speech, just as in contrast with the Biblical phrase to be “cut off ” (found 194 times in KJV) which does not always indicate the literal “physical” act of cutting (Numbers 19:13; Proverbs 2:22; Jeremiah 7:28), but that of a separation (as in discontinuing a relationship, fellowship, etc..).
