Root

ROOT
[n] source [v] establish or tear out

"so that Christ may dwell in your hearts through faith; and that you, being rooted and grounded in love, may be able to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ which surpasses knowledge, so that you may be filled with all the fullness of God" [Eph. 3:17-19; NASB].

"so that Christ may dwell in your hearts through faith--that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, so that you may be filled with all the fullness of God" [Eph. 3: 17-19; ESV].

I decided to look this up--root it up?--subsequent to Bible study and discussion which ensued. It seems that being rooted and grounded in love provides both source and establish[ment] of our life and our growth and our fruitfulness--but I may be misreading this.
