My friends, be glad, even if you have a lot of trouble. You know that you learn to endure by having your faith tested. But you must learn to endure everything, so that you will be completely mature and not lacking in anything.  ~James 1:2-4 (NLT)

For God has not given us a spirit of timidity, but of power and love and discipline. ~ 2 Timothy 1:7 (NASB)
