“I work hard on forgiveness, but sometimes I get to a week in which I do not want to even think about it or what happened to me. During these times, what can I do to not feel guilty or uncomfortable about setting forgiveness aside?”
Let us take an analogy here. Suppose you have a physical fitness regimen. Do you work out every week for an entire year or do you take some time off to refresh, to heal, to re-group? Physical trainers tell us to take some time off. It is good for us. Think of becoming forgivingly fit in the same way. Hard work is good, but we need some time off to refresh and re-group so that we come back to that work with renewed enthusiasm.
