It reminds me of an example I gave in a talk when I was a Witness. I said that if someone knocks you down in the parking lot after the meeting, you have reason to be upset. The person who knocked you down has a problem.
If people come to the next meeting later in the week, you are still on the ground in the parking lot complaining about the person who knocked you down after the previous meeting, now YOU have the problem.
Get up and move on. Don't stay on the ground. Find faith again, and teach others how to get up and walk.
