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, or 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 labour for, or set our hearts on, any thing else, but that which is our proper end, and true happiness?
The Works of Jonathan Edwards, 2:244.
