Do you think you love your children better than He who made them? Is not your love what it is because He put it into your heart first? Have you not often been cross with them? Sometimes unjust to them? Whence came the returning love that rose from unknown depths in your being, and swept away the anger and the injustice? You did not create that love. Probably you were not good enough to send for it by prayer. But it came. God sent it. He makes you love your children.
If you're born in a cubicle and grow up in a corridor, and work in a cell, and vacation in a crowded sun-room, then coming up into the open with nothing but sky over you might just give you a nervous breakdown.
