What came to mind wasn't the typical answer, you know, thinking back to how many times I 'did something'.
Instead, what I recognized is, forgiveness or 'being forgiving' is a constant state that Holy Spirit represents, in which all is seen as already forgiven and that there is nothing 'to' forgive - because forgiveness fore-gives in order NOT to judge.
So this led to recognizing and acknowledging, that perhaps in some way I am 'being forgiving' all the time, to some degree, as a constant thing rather than as one-off events of sudden correction.
See, there's a difference between being forgiving and applying a correction. Correction is there to undo faulty perceptions so that you can RETURN to a forgiving attitude. Yet in the past I used to think forgiveness is the part where you correct the attitude - the process.
So I stopped to get a sense of... am I, in general, having a more forgiving attitude than I used to have.... am I carrying around with me a constantly more forgiving way of perceiving, regardless of whether it's punctuated with "Oh I gotta do something" procedures and techniques. And in general, I don't really know.. but I think I'd have to say yes, I'm generally more forgiving.
In other words, each time a correction is made, I become more forgiving in general and my 'level' of forgiving attitude raises. It's a constant, not a one-off. I'm less judgemental. I'm not as attached. I'm less reactive. I'm generally "stronger in the truth" (Jesus's words to me). That seems like a step in the right direction.
So no need to beat ourselves up for how many linear times we've 'done a forgiveness'... all the benefits of prior efforts stay with us. Each choice for Holy Spirit is a permanent step toward Heaven. And you definitely aren't 'guilty' for not taking enough of them.
