Course I dont mind
1. The simple answer to this question would be yes.
The longer answer would involve quoting Bible passages stating we are "heirs of God, and joint-heirs of Christ", that in my Church we believe in a pre-existence (that we lived with God and Jesus Christ before we came to this Earth), and during this time a plan (often referred to as the plan of happiness, salvation or redemption) was given to us. Those who fully accepted Christ and did all that was expected would receive "all that the Father" has. Even that answer barely explains it all, but I hope it shows the point of why we believe that.
2. In answering the first question, he will at some point. Unless I'm mistaken, the second coming, resurrection and Judgement would need to happen before anyone that came to this Earth was "exalted". So, I guess the quick answer there would be 'not yet'.
3. Yes, Christ's appearance was a physical one. I hope that I am understanding this question properly, but I think the answer is yes.
