God Is the Gospel: Meditations on God's Love as the Gift of Himself - by John Piper

"The acid test of biblical God-centeredness - and faithfulness to the gospel - is this: Do you feel more loved because God makes much of you, or because, at the cost of his Son, he enables you to enjoy making much of him forever?" (pg. 11)

"If the enjoyment of God himself is not the final and best gift of love, then God is not the greatest treasure, his self-giving is not the highest mercy, the gospel is not the good news that sinners may enjoy their Maker, Christ did not suffer to bring us to God, and our souls must look beyond him for satisfaction." (pg. 12)

"When I say that God Is the Gospel I mean that the highest, best, final, decisive good of the gospel, without which no other gifts would be good, is the glory of God in the face of Christ revealed for our everlasting enjoyment." (pg. 13)

"Nothing fits a person to be more useful on earth than to be more ready for heaven." (pg. 16)

"The gospel is not a way to get people to heaven; it is a way to get people to God. It's a way of overcoming every obstacle to everlasting joy in God. If we don't want God above all things, we have not been converted by the gospel." (pg. 47)

"The glory of Christ is not synonymous with raw power. The glory is the divine beauty of his manifold perfections. To see this requires a change of heart." (pg. 54)

"The natural self-centered condition of human hearts cannot believe, because they cannot see spiritual beauty. It is not a physical inability, as though they can't act even if they have a compelling desire to act. It is a moral inability because they are so self-absorbed, they are unable to see what would condemn their pride and give them joy through admiring another. That is why seeing the glory of Christ requires a profound spiritual change." (pg. 54)

"...the glory of God in Christ, revealed through the gospel, is a real, objective light that must be spiritually seen in order for there to be salvation. If it is not seen - spiritually tasted as glorious and precious - Satan still has his way, and there is no salvation." (pg. 64)

"This is the way the Holy Spirit does his ongoing change in us. He does not change us directly; he changes us by enabling us to see the glory of Christ." (pg. 90)

"The purpose of the gospel - both its central events of Good Friday and Easter, as well as their proclamation in the world - is to make the glory of God in Christ the foundation and the means of all salvation and sanctification and glorification. There is no gospel where the glory of God in Christ is not shown. And there is no salvation through the gospel where the glory of God in Christ is not seen." (pg. 97)

"Something else must be present in faith if it is to be saving faith that honors Christ rather than just using him. Saving faith must have a quality to it that tastes what is Christ-exalting and embraces it." (pg. 129)

"...gratitude that is pleasing to God is not first a delight in the benefits God gives (though that will be part of it). True gratitude must be rooted in something else that comes first - namely, a delight in the beauty and excellency of God's character." (pg. 136)

"Divine love labors and suffers to enthrall us with what is infinitely and eternally satisfying: God in Christ." (pg. 155)
