While many lament, I am hesitant. No, I'm definitely not joyful over this. However, I do find it necessary to ponder upon such event involving missionaries.
On the one hand, I am reluctant to call these missionaries. Teaching Korean and computer skills hardly qualify anyone to be a missionary. But it is a common thing nowadays. A Christian goes to do some non-evangelistic related work overseas and he's called a missionary. No wonder people look down on real missionaries these days - after all, they don't have ordinary jobs, they are but beggars, asking converts for money, if not their churches. Many have given missionaries a bad name. It's time for a change.
I don't know about these Koreans, but this incident should not discourage real missionaries. They do not have to come out of Korea or America. Contrary to many elderly, missionaries do not need to wait for churches to send them. The calling of God reveals the power of God, not of men.
