Instead of passively enduring, we persevered in the midst of the storm. As Christians, We can persevere through storms. All the while finding joy in the fact that God is using this process to teach me to trust him. I don't believe the growth is automatic. I believe that the growth and maturity comes only through trusting God through those trials of our faith.
Some people become angry, frustrated or even bitter.
That isn't maturity. Dave Dravecky was a pitcher for the Padres and the Giants. In 1988 he underwent surgery to remove a malignant tumor from his left arm. He was told he would never pitch again. An incredible time of victory and celebration was ended quickly though for in his next game, against Montreal, the bone in his arm snapped.
