Final Instructions and Greetings
Keep your distance from those who would create obstacles for you.
This seems like good advice to me. I've definitely stopped hanging out with people in the past who always seemed to cause problems.
I rejoice in your obedience.
Obedience is an interesting thing. It is really important in some circumstances. But it can also leave you vulnerable. If you are just following someone else's lead, you can wind up working against your own self interest. So obedience is only a virtue if it is coupled with the ability to determine who should be trusted.
I want you to be wise to what is good and innocent to what is evil.
This is interesting too. It sounds good at first blush, "know about good things, ignore evil things". Sometimes I'll read a disturbing news article and wish I hadn't read it. I often won't share the story with my wife, why have that garbage rolling around in her head too? In that way, I can see how being ignorant of evil is a good thing. On the other hand, it can leave you vulnerable. If someone is trying to scam you, they will have a much harder time if you are familiar with the tricks that are employing.
An ancient secret has finally be revealed, obedience and faith are the most important thing.
I think my comments above reveal my thoughts on that.
