Repent = turn from, right?
So, how often we repent is measured in how often we stayed "turn from."
I turned from getting high twice, because I turned back once.
I turn from holding a grudge more often, because I keep noticing, even when I don't mean to, or forget, that I end up turning back to the grudge again. By nature, I'm very good at keeping a grudge, so it is more of a habit to keep it, than repent from it. The day I don't turn back to the grudge is a day I don't have to repent.
Being raised a good Catholic girl, I'm still stuck with some of the imagery I was taught as a kid. Sometimes it serves me well. Back then I was told to "lay my sins at the foot of the cross/at Jesus' feet and leave them for him." So all these decades later, when I'm turning from a sin, I still picture myself giving a broken down old box of junk onto the ground right in front of that cross. (Actually, I tend to see his bloody, nailed feet right above the box.) And then somewhere along the line, I notice I've taken it back. Then I have to put it back where it belongs, and repeat as necessary.
A few of the boxes I laid down long ago, they've gotten soggy, and disintegrated for so long, I barely remember what was in those boxes. Many of them need to be returned there often, so at least I still see what's in them. The plan is to let them rot there, instead of feeling like I'm a hoarder. Depends on when you catch me to ask me how I'm doing. Most the time I feel like a hoarder, but occasionally I notice something I'm no longer hoarding.
