that you may know the love of Christ

This is the second thing that Paul prays that the Ephesians will be able to do; the first is that they "understand." Alternate translation: "that you can know how great Christ's love for us is"

that you may be filled with all the fullness of God

This is the third item for which Paul bends his knees and prays (Ephesians 3:14). The first is that they would "be strengthened" (Ephesians 3:16), and the second is that they "can understand" (Ephesians 3:18).
