"That we ought not to rest in the world and its enjoyments, but should desire heaven. We should “seek first the kingdom of God.” (Mat. 6:33) We ought above all things to desire a heavenly happiness; to be with God and dwell with Jesus Christ. Though surrounded with outward enjoyments, and settled in families with desirable friends and relations; though we have companions whose society is delightful, and children in whom we see many promising qualifications; though we live by good neighbors, and are generally beloved where known; we ought not to take our rest in these things as our portion. We should be so far from resting in them, that we should desire to leave them all, in God’s due time. We ought to possess, enjoy and use them, with no other view but readily to quit them, whenever we are called to it, and to change them willingly and cheerfully for heaven.
"God is the highest good of the reasonable creature, and the enjoyment of him is the only happiness with which our souls can be satisfied. — To go to heaven fully to enjoy God, is infinitely better than the most pleasant accommodations here. Fathers and mothers, husbands, wives, children, or the company of earthly friends, are but shadows. But the enjoyment of God is the substance. These are but scattered beams, but God is the sun. These are but streams, but God is the fountain. These are but drops, but God is the ocean. — Therefore it becomes us to spend this life only as a journey towards heaven, as it becomes us to make the seeking of our highest end and proper good, the whole work of our lives, to which we should subordinate all other concerns of life. Why should we labor for, or set our hearts on anything else, but that which is our proper end, and true happiness?"
Jonathan Edwards
