Do not pray for easy lives. Pray to be stronger men. Do not pray for tasks equal to your power but for power equal to your tasks. Then doing of your work shall be no miracle but you shall be a miracle yourself. Everyday you shall wonder at yourself, at the richness of life that has come to you by the grace of god. Not in doing what you like but in liking what you do lies the secret of happiness.

God has not promised
skies always blue,
Flower-strewn pathways
All our life through;

God has not promised
Sun without rain,
Joy without sorrow,
Peace without pain.

But God has promised
Strength for the day,
Rest for the labour
Light for the way.
