Spurgeon says, “It’s not thy joy in Christ that saves thee; it’s Christ. It’s not thy hope in Christ that saves thee; it’s Christ. It’s not even thy faith in Christ, though that be the instrument; it is Christ’s blood and merit.” That’s where the power is and that’s where the salvation is. Now Paul’s not talking about faith when he says “and that, not of you.” Well God says “the gift.” He’s talking, rather, about salvation and salvation is a gift that eliminates boasting. Everything about it is God.
