The Psalms are an everlasting manual to the soul; the book of its immortal wishes, its troubles, its aspirations, and its hopes; sung in every tongue… - Henry Giles

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 illusions are over, when the distractions of sense, the vagaries of fancy, and the tumults of passion have dissolved even before the body is cold, which once they so thronged and agitated, the soul merges into intellect, intellect into conscience, conscience into the unbroken, awful solitude of its own personal accountability; and though the inhabitants of the universe were within the spirit's ken, this personal accountability is as strictly alone and unshared, as if no being were throughout immensity but the spirit and its God.

Brethren, we can rule our tempers, and we ought. Open the gospel, that most profound philosophy of the human soul, and yet most simple and practical directory of human duty; study it, fill your whole nature with its inspiration; set Christ before you; look upon His calm forehead and unstormed breast; think how He endured all contradiction of sinners, and endured them to the cross; and on the cross learn of Him then, for He was meek and lowly of heart.
