There is one God and one mission for all people (Romans 3:29–30; Galatians 3:26–29). The phrase one God is a key statement of Christian faith, similar to the basics of Jewish faith (Deuteronomy 6:4).
there is one mediator between God and men, the man Christ Jesus: Jesus is fully human and fully God. This means he is the only one who can make peace between God and humanity (see 1 Corinthians 8:6; Ephesians 4:5–6).
