I was a missionary to Japan for 33 years. I did not have special gifts to do that. It was all involved in how God made me. He made me to love the Japanese people and their culture and language.
This is where you and I differ I think - I believe that you must have had gifts to do that - maybe you don't recognize them and maybe that is because we tend to have an elevated opinion of what is a gift, for example we might speak of a gifted preacher, meanings he is one of the best - but I would suggest that every genuine preacher is exercising a gift of God in preaching.
So, whilst I don't know what you did in Japan I do imagine it took some gifts to do it
Take the language--please! It's a very difficult one. However, it was duck soup for me. God had made me with an aptitude for languages. Call that a gift if you wish, but it was in my DNA, so I don't consider that it was a gift, somehow given to me, but simply part of who I am.
And didn't God make you into who you are?
Because there are no such gifts listed in Eph. 4. The context says "gifts," but then the roles/offices are "given," making them the gifts. That's kind of what I've been saying--that the men in Eph. 4:11 are the gift. There is no indication in the passage, though, that there are specific gifts that make being a pastor easier. I think you'd have to go to the Corinthian or Roman passages for specific gifts, but none of those gifts are a gift of evangelism. Yet if there were a special gift of evangelism, wouldn't you expect to find it in those passages?
As I said, I believe the large issue here is our difference in what is 'a gift' - you see yourself as operating in a certain role without specific gifts - but I see you as having to have exercised gifts whether you realized it or not - I suggest therefore that we are talking across each other to some degree
