The problem with Camping and his ilk is that over time they have to be more and more "out there" in order to stay relevant. From all I've read, Camping was fairly mainstream albeit with a strong Calvinist leading, which inevitably leads to a fatalistic view. He's gradually moved from any accountability and gotten himself further and further out on a limb, with no one to help him down out of the tree.
Here's my real point... after 63 years, I've learned that what God wants is a relationship (Romans 5:8!). I've left all of the pre-trib, post-trib, and a thousand other theological explanations and just live every day thankful that the Creator of the universe WANTS to have a personal relationship with me.
I think God approaching Adam and Eve after their sin speaks to what God truly wants from us ...dependence on Him.
I'll leave the preaching to the preachers; many, like Camping, who serve to make the simple complex and I'll just continue to be thankful that God makes it all so simple.
Also, you mentioned living a contented life with an attitude of gratitude. Very important!
I may be more interested than you are about end times but that is OK God does not use a cookie cutter when he makes us. Just know this, which I already know you do based on your testimony, that when things hit the fan, as I think they will IMHO know that Our Lord Jesus Christ can handle it.
