The gospel of Jesus Christ is a gospel of grace. It is unique from the religions of the world in that it does not require a person to live by a set of rules to obtain salvation.
When other religions say do this, Christ says done.
Christ has already done all of the work for your salvation. All you have to do is call upon the name of Lord Jesus Christ and accept the salvation that He has provided. This is the message of the gospel of Jesus Christ that is preached by every Christian in the way they live their lives and the words that they say.
Rejoice as Paul tells us about God's grace and our release from the legalist's rules and rituals in this verse-by-verse study of 2 Cor. 3:17-4:2
