" You do not know how much you owe to God for giving you rest at night. If you had sleepless nights, you would then value the blessing. If for weeks you lay tossing on your weary bed, you then would thank God for this favor. As sleep is the merciful appointment of God, it is a gift most precious, one that cannot be valued until it is taken away – and even then, we cannot appreciate it as we should. "

― Charles Haddon Spurgeon , Faithful to Christ: A Challenge to Truly Live for Christ
