You can smile in every trial because of what you have in Christ.
1 Peter 1: 6-8 In all this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that the proven genuineness of your faith of greater worth than gold, which perishes even though refined by fire may result in praise, glory and honor when Jesus Christ is revealed. Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy.
