Brothers, receive Christ as your Lord and your Savior and your Treasure, for this is what it means to believe the gospel. Below is an awesome description of what "God is the gospel" means as well as the meaning of "The love of God is the gift of himself." It comes from America's greatest theologian Jonathan Edwards in 1731, when he was 28.
"The redeemed have all their objective good in God. God himself is the great good which they are brought to the possession and enjoyment of by redemption. He is the highest good, and the sum of all that good which Christ purchased.
God is the inheritance of the saints; he is the portion of their souls. God is their wealth and treasure, their food, their life, their dwelling place, their ornament and diadem, and their everlasting honor and glory. They have none in heaven but God; he is the great good which the redeemed are received to at death, and which they are to rise to at the end of the world. The Lord God, he is the light of the heavenly Jerusalem; and is the "river of the water of life" that runs, and the tree of life that grows, "in the midst of the paradise of God."
The glorious excellencies and beauty of God will be what will forever entertain the minds of the saints, and the love of God will be their everlasting feast. The redeemed will indeed enjoy other things; they will enjoy the angels, and will enjoy one another: but that which they shall enjoy in the angels, or each other, or in anything else whatsoever, that will yield them delight and happiness, will be what will be seen of God in them.
