'In Me' in the Bible

But God, who is rich in mercy, for his great love wherewith he loved us,

in which I have been appointed to serve, in virtue of the work which God, in the exercise of His power within me, has graciously entrusted to me.

from whom all the body, being fitted and knit together through that which every joint supplies, according to the working in measure of each individual part, makes the body increase to the building up of itself in love.
