"So then, brothers, we are debtors, not to the flesh, to live according to the flesh. For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live. For all who are led by the Spirit of God are sons of God."
(Romans 8:12-14 ESV)
"Let us give up the government of our souls to the Spirit. It is for our safety so to do, as being wiser than ourselves who are unable to direct our own way. It is our liberty to be under a wisdom and goodness larger than our own. Let the Spirit think in us, desire in us, pray in us, live in us, do all in us; labor ever to be in such a frame as we may be fit for the Spirit to work upon."
(Richard Sibbes, from A Fountain Sealed)
