Some pastors from the north of Vietnam have known me through our students and some of them attended the bible courses that I taught online (Zoom) in a bible school. There was one thing in common with them - that they contacted me and asked for me to train them. I considered this a "Macedonian call". This reminds me the account of Paul in Acts 16, “.. a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him saying, Come over into Macedonia, and help us.” (v.9).
Unlike apostle Paul, there was no vision that appeared to me, but I had phone calls and messages via Messenger or Zalo saying “Come and help us.” I believe that those are evidence of a call or vision. Compared to years ago, I had no contact nor knew how to start to help churches there. But right now, my concern is how to get more teachers to train church workers and leaders in the northern region.
