Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord, Grace - God's favor; peace - the effects of that favor in the communication of spiritual and temporal blessings.
Through the knowledge of God - Εν επιγνωσει· By the acknowledging of God, and of Jesus our Lord. For those who acknowledge him in all their ways, he will direct their steps. Those who know Christ; and do not acknowledge him before men, can get no multiplication of grace and peace.
