Repentance itself is nothing else but a kind of circling: to turn to the One by repentance from whom, by sin, we have turned away.
First, then, there is a turn in which we look forward to God and with our whole heart resolve to turn to God. Then there is a turn again in which we look backward to our sins in which we have turned from God; and with beholding them our very heart must break. There is one turn resolving to amend that which is to come; another reflecting and sorrowing for that which is past; one turn declining from evil to be done hereafter, another sentencing itself for evil done before.
To turn is a counsel given to those are out of the right way, for going on still and turning are opposite motions, both of them with reference to a way. It the way is good, we are to hold on; if otherwise, to turn and take another.
