I started the forgiveness process but out of sheer fatigue, I stopped for a while. I want to start up again and now I have a question. Should I start at the beginning or continue where I left off?
This depends on how long it has been since you previously were practicing forgiveness. If you have left the process for a few weeks, I suggest that you start at the beginning. This does not mean that it will take you a long time to get to where you left off. Some of the challenges in the early part of forgiveness (such as uncovering the effects of resentment) likely will be confronted quickly so that you can keep going in the forgiveness process.
