I have been serving at church for 20 years but still find myself owe God a lot, especially in the area of faithfulness and biblical knowledge. Indeed I didn't understand the relationship between the Law and the grace until I listened to Galatians, the Voice of Friendship Seminary programs several months ago. Some old believers in my church turned to the Lord when they were sick. God did heal them but they lay their faith on miracles only. When they fall in illness again, they don't take medicine or see doctor.
Medical treatment is regarded as faithless act in their eyes.
I know a sister has been suffering from serious illness for a long time. Her parents dare not taking her to hospital for the sake of church reputation. Our church has not yet registered and is facing persecution. Once, while we were worshipping God, around twenty people broke in and took away our benches, books and some belongings. I always consider Daniel's loyalty and obedience an excellent example for us.
