For it is all for your sake, so that as grace extends to more and more people it may increase thanksgiving, to the glory of God.
2 Corinthians 4:15

Grace is not a super power bestowed on people by the Holy Spirit. Rather, it is a quality of God himself and of his behavior towards mankind. Grace is essentially a synonym for longsuffering kindness and forgiveness. The more people to whom God extends his grace, the more people receive forgiveness and enjoy freedom from well-deserved condemnation.
