Joy and Sorrow From Lord of the Rings, book three. As Gandalf and Pippin gaze out over Gondor, on the eve of the battle. Are you angry with me, Gandalf?' he said, as their guide went out and closed the door. 'I did the best I could.' 'You did indeed!' said Gandalf laughing suddenly; and he came and stood beside Pippin, putting his arm about the hobbit's shoulders, and gazing out of the windows. Pippin glanced in some wonder at the face now close beside his own, for the sound of that laugh had been gay and merry. Yet in the wizard's face he saw at first only lines of care and sorrow; though as he looked more intently he perceived that under all there was a great joy: a fountain of mirth enough to set a kingdom laughing, were it to gush forth.' This is life as a Christian. We go through times of sorrow but through it all is a deep abiding joy that comes from Christ in you the hope of glory.
Psalm 127:3 "Behold, children are a heritage from the Lord, The fruit of the womb is a reward."
