In vain do they talk of happiness who never subdued an impulse in obedience to a principle. He who never sacrificed a present to a future good, or a personal to a general one, can speak of happiness only as the blind do of colors.
The sacrifices required in the Christian life are necessary to emancipate the soul, and raise it above its servile dependence on condition. They are losses of mere happiness, and for just that reason they are preparations of joy.
It is a great truth, wonderful as it is undeniable, that all our happiness—temporal, spiritual, and eternal—consists in one thing; namely, in resigning ourselves to God, and in leaving ourselves with Him, to do with us and in us just as He pleases.
Happiness is neither within us nor without us, it is the union of ourselves with God.
—Pascal.
Happiness is not the end of duty, it is a constituent of it. It is in it and of it; not an equivalent, but an element.
When we are not too anxious about happiness and unhappiness, but devote ourselves to the strict and unsparing performance of duty, then happiness comes of itself—nay, even springs from the midst of a life of troubles and anxieties and privations.
—Humboldt.
So long as you do not quarrel with sin, you will never be a truly happy man.
