A.W. Tozer emphasizes that the New Testament message of salvation extends beyond mere pardon for sins; it encompasses repentance, righteousness, and a call to live a godly life. He stresses that accepting Christ as Savior also requires a commitment to deny ungodliness and worldly desires, highlighting the importance of living in accordance with God's kingdom. Tozer warns against the danger of preaching only parts of the gospel, as it dilutes its power and effectiveness. The full gospel includes a call to amendment, separation from worldly influences, and loyalty to God, even in the face of adversity.
