1 Peter 1:6-7

Be glad about this, even though it may now be necessary for you to be sad for a while because of the many kinds of trials you suffer. Their purpose is to prove that your faith is genuine. Even gold, which can be destroyed, is tested by fire; and so your faith, which is much more precious than gold, must also be tested, so that it may endure. Then you will receive praise and glory and honour on the Day when Jesus Christ is revealed.
