There is great treasure in the spirit of the born-again Christian. God, Himself, indwells those who have repented of sin and asked Jesus to be their Lord and Savior.
I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me. John 17:23 KJV
This why we can manifest the life giving, delivering, healing power of God and say,
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. Galatians 2:20 KJV
