PSALM 4:8 I will both lay me down in peace, and sleep:

We know each other’s appearance, but there for the most part our mutual knowledge ceases. It is possible to live on terms of even close intimacy with a person for many years, and yet to find, by some chance uplifting of a curtain in his life, that he cherished feelings which you never even suspected, suffered pains of which you had seen no trace, or enjoyed pleasures which never came to any outward expression. The bitterness which surges in our brother’s heart would probably be unintelligible to us if he revealed it, but he will not reveal it, he cannot. And yet we all hunger for sympathy. No human being needs to be misunderstood, or to suffer under the sense of misunderstanding. Let him turn at once to God. If he cannot tell his bitterness to his fellows, he can tell it to God. No human being need imagine that he is unappreciated; his fellow-men may not want him, but God does. No human being need be without a sharer of his joy. And that is a great consideration, for joy unshared quickly dies, and is from the beginning haunted by a vague sense of a shadow that is falling upon it. In the heart of the Eternal dwells eternal joy. All loveliness, all sweetness, all goodness, all truth, are the objects of His happy contemplation; therefore every really joyful heart has an immediate sympathiser in God, and prayer is quite as much the means by which we share our gladness as the vehicle by which we convey our sorrows to the Divine heart.
