A common term for Mormonism or its intricate plan of salvation. "The gospel is our Heavenly Father's plan of happiness. ... In its fulness, the gospel includes all the doctrines, principles, laws, ordinances, and covenants necessary for us to be exalted in the celestial kingdom. The Savior has promised that if we endure to the end, faithfully living the gospel, he will hold us guiltless before the Father at the Final Judgment" (True to the Faith, p. 76).
The LDS Church teaches that the gospel was restored in its fullness during these latter days through the Prophet Joseph Smith. By following the LDS gospel, a person can find happiness in this mortal life and eternally progress toward happiness in eternal life. Obedience, not faith, is a hallmark of following the gospel.
Biblical Christianity teaches that the gospel is the specific good news that Jesus has done everything for our salvation (1 Corinthians 15:1-7). It is the power of God for the salvation of all who believe (Romans 1:16).
