“Grow in Grace” is no understatement. It means we continue to be like a tree, (Planted by the living waters) Growing fruit in our lives as a living being IN HIM. No tree ever grew better from having a list of rules read to it, or being read the riot act.
God plants (his word in you) and he will surely water it and cause it to grow. Our job is surrender, Trusting Him, Believing in Him (for all things) And even Self-Control is a fruit of the Spirit, and not a work of the flesh. (See Galations).
Think about that for a moment! “Hello there, righteous little tree!
God loves you, SO MUCH!”
2 Peter 3:18 “but grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory, both now and to the day of eternity.” Amen.
