We are taught and supposed to forgive. That is a given if we want forgiveness, too.
But to what extent do you forgive others for their past and and current actions? Are you worried past actions will repeat themselves? How much do you put yourself out there for someone based on the extent forgiveness for the other person is needed?
Yes! I have to lean on my faith for forgiveness from God when my forgiveness runs short. Ultimately it is His forgiveness that is most important.
