It must be understood that it is the duty of all Christians to strive always and in every way to be united with God, their Creator, Lover, Benefactor, and their supreme good, by whom and for whom they were created. This is because the center and the final purpose of the soul, which God created, must be God Himself alone, and nothing else—God from whom the soul has received its life and its nature, and for whom it must eternally live.
For all visible things on earth which are loveable and desirable—riches, glory, wife, children, in a word everything of this world that is beautiful, sweet, and attractive—belong not to the soul but only to the body, and being temporary, will pass away as quickly as a shadow. But the soul, being eternal by its nature, can attain eternal rest only in the eternal God: He is its highest good, more perfect than all beauty, sweetness, and loveliness, and He is its natural home, whence it came and whither it must return.
For the soul was created by God in order to dwell with Him forever; therefore, in this temporary life we must diligently seek union with God.
