grow in the grace and knowledge of our Lord and Savior Jesus Christ

Here growing in the grace and knowledge of the Lord represents experiencing his grace more and knowing him more. The abstract noun "grace" can be expressed with the phrase "act kindly." Alternate translation: "receive more of the grace of our Lord and Savior Jesus Christ, and know him more" or "be more aware of how our Lord and Savior Jesus Christ acts kindly toward you, and know him better" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-abstractnouns)
