I will not excuse them that fall in the likings and delights of gluttony and lechery, as if they sinned not; for I wot well that all the kinds of them are sins more or less, according to the measure of the lust and misbehaviour in the sin, and other likings, with consideration of how far voluntary it was with other circumstances. But my desire is, that thou mightest know and esteem all sins according as they are, indeed, the greater to be the greater, as are spiritual sins; and the less to be the less, as are fleshly or sensual sins; and yet nevertheless would I have thee to hate and fly all, both bodily and spiritual, with all thy might.(John Climacus)

Which comes first, to hate sin with all thy might or to seek the grace of God with all thy being?

Perhaps it depends on the person. Depending on our own experience - and especially on our state of pride - embracing our own flaws and failures may be a pre-requisite to grace.

But in one way or another, at some time or another, our attention must shift to seeking and accepting the grace of God.
