James 4:4-6. Man’s natural pursuit is for his own glory and pride and not the glory of God. Despite this sin, God gives more grace to Christians.
Galatians 2:17-21. Paul argues for the complete justification found in the gospel and not a mix of grace plus works. This is an impossibility. To do so makes Christ’s work on the cross in vain.
Galatians 2:15-16. The center of Christianity is the gospel. At the center of the gospel is justification. Right standing before God is found by grace alone, through faith alone, in Christ alone.
