Why? Most probably don't even consider it. The thought has simple never crossed their mind. It's not bad, it just is. I got the idea to meet missionaries overseas directly (I believe) from God. I didn't think of it and to my knowledge no one put the thought in my head. Therefore, it is just something that happened. Since I believe that information came from God, it would be difficult to assume other Christians would get that same message, or at least the same message the same way I got it.
Yet I did get that message, and it's something I've enjoyed doing. I get to have a finger on the pulse of missions, get to strengthen my own faith, and get to see parts of a city that most people don't get to see.
