And believing the gospel is not the only requirement to enter the holy city. (See Philippians 1:29).
*Romans 1:16 - For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek. 1 Corinthians 1:21 - For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe.
