"For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek." Romans 1:16

A.W. Tozer said what you think of when you think of God is the most important thing about you. Steve Lawson said what you think of Jesus is the most important thing about you. Your understanding and grasp of the gospel affects how you relate to God, yourself, and others. Get the gospel right and you can live and share it right. Get it wrong and things get tweaked.
