Albert Barnes Commentary Ephesians 3:17

"that Christ may dwell in your hearts through faith; to the end that ye, being rooted and grounded in love," — Ephesians 3:17 (ASV)

That Christ may dwell in your hearts by faith. (See the notes on Ephesians 2:22).

Expressions like this often occur in the Scriptures, where God is said to dwell in us, and we are said to be the temples of the Holy Ghost. (See the notes on John 14:23; 1 Corinthians 6:19).

That you being rooted. Firmly established—as a tree is whose roots strike deep, and extend far. The meaning is, that his love should be as firm in our hearts as a tree is in the soil, whose roots strike deep into the earth.

And grounded. teyemeliwmenoi—founded—as a building is on a foundation. The word is taken from architecture where a firm foundation is laid. The meaning is that he wished them to be as firm in the love of Christ as a building that rests on a solid basis.

In love. In love to the Redeemer—perhaps also in love to each other and to all. Love was the great principle of the true religion, and the apostle wished that they might be fully settled in that.
