Read this little selection, and then go read his sermon “The Christian Pilgrim“:
“Heaven is that place alone where our highest end and highest good is to be obtained. God hath made us for himself. “Of him, and through him, and to him are all things.” Therefore, then do we attain to our highest end, when we are brought to God: but that is by being brought to heaven, for that is God’s throne, the place of his special presence. There is but a very imperfect union with God to be had in this world, a very imperfect knowledge of him in the midst of much darkness: a very imperfect conformity to God, mingled with abundance of estrangement. Here we can serve and glorify God, but in a very imperfect manner: our service being mingled with sin, which dishonors God. — But when we get to heaven (if ever that be), we shall be brought to a perfect union with God and have more clear views of him. There we shall be fully conformed to God, without any remaining sin: for “we shall see him as he is.” There we shall serve God perfectly and glorify him in an exalted manner, even to the utmost of the powers and capacity of our nature. Then we shall perfectly give up ourselves to God: our hearts will be pure and holy offerings, presented in a flame of divine love.
“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?”
