There is another reason to forgive quickly and to forgive for all time. It is the experience of suffering (frequently mental suffering) that comes from inner turmoil when relationships are going poorly. Why does suffering sometimes come in the immediate future, following a distasteful altercation, even suffering that later may lead to God? This is one of those thorny issues, but Jesus has an answer for us. He sees time and space as a continuum of illusion, all of one piece.
So the delay in time for the good is caused by the separation that we would yet see between our brother and ourselves. Jesus sees this separation as “little space that lies between you, unforgiven still.” (T-26.VIII.8:3) And he concludes, “Be not content with future happiness.” (T-26.VIII.9:1) In a word, if our forgiveness of our brother is complete now, our rewards of happiness now will be met. The Holy Spirit, being outside time and space, gives consequence and cause as one. But, we are told, “The working out of all correction takes no time at all. Yet the acceptance of the working out can seem to take forever.” (T-26.VIII.6:1-2)
We are pulled back to realize that it is the little “space” between ourselves and our brother, disguised as time, that is the culprit here. And that little space has been primed by attack.
