Consider it pure joy, my brothers, whenever you face trials of many kinds, because you know that the testing of your faith develops perseverance...Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him. -James 1:2 and 12

...Though now for a little while you may have had to suffer grief in all kinds of trials.  These have come so that your faith--of greater worth than gold, which perishes even though refined by fire--may be proved genuine and may result in praise, glory and honor when Jesus Christ is revealed. -1 Peter 1:6-7
