A tried  christian is the one who can persuade people that even in great affliction, still... managed to say to the Lord " thank you for choosing me , i knew that you will work in wonders"

Of being a teacher is not an unpleasant choice! It's a choice of passion! Attack teaching with renewed zeal. Whatever you see from anywhere could be of good help while teaching. Teacher's ministry is to share valuable experiences, and derive something out of pupils predicament so that, they too will be able to explore on things which they need to know.
