Ephesians 3:17

That Christ may dwell in your hearts by faith - In this as well as in many other passages, and particularly that in Ephesians 2:21 (note), the apostle compares the body or Church of true believers to a temple, which, like that of Solomon, is built up to be a habitation of God through the Spirit. Here, as Solomon did at the dedication of the temple at Jerusalem, 2 Chronicles 6:1, etc., Paul, having considered the Church at Ephesus completely formed, as to every external thing, prays that God may come down and dwell in it. And as there could be no indwelling of God but by Christ, and no indwelling of Christ but by faith, he prays that they may have such faith in Christ, as shall keep them in constant possession of his love and presence. God, at the beginning, formed man to be his temple, and while in a state of purity he inhabited this temple; when the temple became defiled, God left it. In the order of his eternal mercy, Christ, the repairer of the breach, comes to purify the temple, that it may again become a fit habitation for the blessed God. This is what the apostle points out to the believing Ephesians, in praying that Christ κατοικησαι, might intensely and constantly dwell in their hearts by faith: for the man's heart, which is not God's house, must be a hold of every foul and unclean spirit; as Satan and his angels will endeavor to fill what God does not.

That ye, being rooted and grounded in love - Here is a double metaphor; one taken from agriculture, the other, from architecture. As trees, they are to be rooted in love - this is the soil in which their souls are to grow; into the infinite love of God their souls by faith are to strike their roots, and from this love derive all that nourishment which is essential for their full growth, till they have the mind in them that was in Jesus, or, as it is afterwards said, till they are filled with all the fullness of God. As a building, their foundation is to be laid in this love. God so loved the world, that he gave his only begotten Son, etc. Here is the ground on which alone the soul, and all its hopes and expectations, can be safely founded. This is a foundation that cannot be shaken; and it is from this alone that the doctrine of redemption flows to man, and from this alone has the soul its form and comeliness. In this, as its proper soil, it grows. On this, as its only foundation, it rests.

That Christ may dwell in your hearts by faith - see the notes, 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 Spirit; see the John 14:23, note; 1 Corinthians 6:19, note.

That ye being rooted - Firmly established - as a tree is whose roots strike deep, and extend afar. 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 - θεθεμελιωμένοι tethemeliōmenoi - "founded" - as a building is on a foundation. The word is taken from architecture, where a firm foundation is laid, and the meaning is, that he wished them to be as firm in the love of Christ, as a building is 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.

3:17 Dwell - That is, constantly and sensibly abide.
