If you would test the character of anything, you only need to enquire whether that that thing leads you to God or away from God.
From James 1:2-4: “My brothers and sisters, whenever you face various trials, consider it all joy, because you know that the testing of your faith produces endurance. And let endurance complete its work, so that you may be complete and whole, lacking in nothing.”
Watchman Nee (1903-1972) was a Chinese church leader and Christian teacher. He authored a collection of Christian books, and he endured persecution for his beliefs. Ultimately, he died while being imprisoned for the final twenty years of his life.
