Sorry to intrude. John Dehlin here.
Some quick answers:
1) I am active in the church. My wife and I teach primary together.
2) I do currently hold a temple recommend
3) I consider myself to be a believer in God, and in Jesus. I also view the church and the Book of Mormon as inspired -- although I struggle sometimes with how literal vs. symbolic/metaphorical these beliefs are.
In the end....I choose to follow/believe....I continually have doubts/concerns...but I plan to remain an active, committed member until the day I die.
I can't say that I know anything (church related), but I hope for most of the typical gospel related things (purpose in life, life after death, that the "truth" can be found, that I'll be with my family in heaven) -- and I consider my active membership in the church to be an act of faith in and of itself...accompanied by many, many doubts.
All in all, I love the church, I love its members, and I love being Mormon.
