Believers have experience of the power and efficacy of indwelling sin. They ﬁnd it in themselves; they ﬁnd it as a law. It has a self-evidencing efficacy to them that are alive to discern it. They that ﬁnd not its power are under its dominion. Whosoever [would] contend against it shall know and ﬁnd that it is present with them, that it is powerful in them. He shall ﬁnd the stream to be strong who swims against it, though he who rolls along with it be insensible of it.
