2J, this is from 12 years now in biker ministry, okay?
I think it is normal and healthy to have a skeptical heart. Forgiveness is a decision. Trust is something that is earned by lifestyle. And in all these years of biker and prison ministry I have found out that a lot of people will try to dupe you and will disappoint you if you let 'em.
But, the ones that actually don't - and end up being genuine, really make the it worth giving the chances.
Nope, that don't mean giving them the keys to the church or anything! LOL Be skeptical, but show love and forgiveness - with the knowledge that something bad may happen - it just makes it all that much better when somebody proves you wrong.
Sounds like to me that's exactly what ya'll are doing. I am sure that your pastor is a wise enough man to know this. Those people that have proven true in their life-change have proven to be some of my most treasured friends!
