I received the following comment:

“…nor did I go up to Jerusalem to those who were apostles before me; but I went to Arabia, and returned again to Damascus.”  (Galatians 1:17)

Not really a question, but possibly a cool thought— When Paul “went to Arabia”, maybe he spent his time at Mt. Sinai.  4:25 references Hagar being a partaker from Mt. Sinai in Arabia, so I thought that Paul may have taken it back to where the Lord spent a good amount of time with one of the other studs of the Bible, Moses.  I’m assuming it’s a possibility—have you ever thought of that—any thoughts?

That is a cool thought, and definitely seems like a possibility. It is very interesting that God would send him to Arabia, as you say. Cornelius Stam wrote a book comparing Paul and Moses. There are some obvious comparisons between the two. It would make sense if Paul met with Christ on Mount Sinai, just like Moses did. Ultimately, of course, it is just speculation, as we don’t know where Paul met with the Lord. Yet it does seem a tempting possibility, with him being in Arabia. David Hettema speculates that when Israel is gathered to meet the Lord in the wilderness at the start of the kingdom, that the place they will be called to is Mount Sinai. Again, there is no proof, but it does seem an interesting and likely possibility.
