The greetings says that the triune God gives grace…and peace.
Grace
is God’s favour, his divine smile (see Numbers 6:25) directed to his servants due to the forgiveness of sins graciously granted to undeserving sinners on account of Jesus’ sacrifice on the cross. The term peace
denotes that the bond between God and sinners is full of harmony.
