This is the second item for which Paul prays that God will "grant" the Ephesians "according to the riches of his glory." The first is that they would "be strengthened" ([Ephesians 3:16](./16.md)).
Here "heart" represents a person's inner being, and "through" expresses the means by which Christ lives within the believer. Christ lives in the hearts of believers because God graciously allows them to have faith. AT: "that Christ may live within you because you trust in him" (See: [[rc://en/ta/man/translate/figs-metonymy]])
Possible meanings are 1) "faith. I pray that you will be rooted and grounded in his love so that you can understand" or 2) "faith so you will be rooted and grounded in his love. I also pray that you can understand"
# that you will be rooted and grounded in his love
Paul speaks of their faith as if it were a tree that has deep roots or a house built on a solid foundation. AT: "that you will be like a firmly rooted tree and a building built on stone" (See: [[rc://en/ta/man/translate/figs-metaphor]])
