What does the Bible say about the genuine gospel?

The genuine gospel, as described in Romans 1, proclaims the righteousness of God, which is revealed through faith in Christ. It is by God's grace that we realize we are called to be saints, and through Jesus Christ, we find salvation. The gospel holds that our faith, given by God, works as the means through which we experience His power for salvation, emphasizing that it is not by our own works but solely by faith in Jesus Christ's finished work. This is encapsulated in the statement that 'the just shall live by faith.'
