What Does the Gospel Teach?

Francis Turretin wonderfully summarizes the heart of the gospel message: "The gospel teaches that what could not be found in us was to be sought in another, and could be found nowhere else than in Christ, the God-man; who taking upon himself the office of surety most fully satisfied the justice of God by his perfect obedience and thus brought to us an everlasting righteousness by which alone we can be justified before God; in order that covered and clothed with that garment . . .we may obtain under it the eternal blessing of our heavenly Father."
