Below is a blurb that Francis Chan wrote on his experience in Asia and things that God taught him through that time:

It was a wonderful time of ministry and learning for my family and me. I learned so much from the believers overseas. There is a focus and a seriousness that comes with persecution. I was deeply influenced and encouraged by our brothers and sisters in difficult situations.

I believe the Lord is teaching me that we can and must have that kind of devotion to him even in a place where there is little persecution.
