"Rejoice in the Lord always. Again I will say, rejoice!" (Phil. 4:4) "Do not sorrow, for the joy of
the LORD is your strength." (Neh. 8:10)
The Christian is joyful, not because he is blind to injustice and suffering, but because he is convinced that these, in the light of the divine sovereignty, are never ultimate. The humor of the Christian is not a way of denying the tears, but rather a way of affirming something which is deeper than tears. Yes, a few things in life are absolutely tragic, no question about it. First among them, is a joyless Christian. (From The Finishing Touch, by Charles Swindoll, p. 65)
