Ephesians 6:23

Peace, love, and faith are all important communal virtues in the Christian life. Peace was necessary because of the Jewish Gentile problems Paul wrote Ephesians to ameliorate (Ephesians 2:14-16; Ephesians 3:15; Ephesians 3:19; Ephesians 4:3). Mutual love is the key to peace (Ephesians 1:15; Ephesians 3:17-18; Ephesians 4:2; Ephesians 4:16), and mutual love rests on a common faith (Ephesians 1:15; Ephesians 3:17; Ephesians 4:5; cf. Galatians 5:6). The ultimate source of all three of these essential qualities is God and Jesus Christ, united here in perfect equality.
