[Sean]

"God inside Christ"(Holy Ghost) was prior to the foundation of the world.(Christ always existed, mind/will of God)

The Holy Ghost was/is comprised of the human spirit of Christ indwelled by the Holy Spirit.

Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.

But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.

But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
