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, 1 Peter 1:6-8 (NIV)
True joy is not the absence of grief or suffering. It's more the result of a faith that has been tested and tried by grief and suffering, resulting in the praise, glory and honor in the revelation of Jesus Christ. Even though we may not be able to see that end result, we are filled with an inexpressible and glorious joy! And that is my unswerving hope!
