Ephesians 3:13

That ye faint not] It might mean 'that I may not faint.' But St. Paul is not afraid of losing heart; he rejoiced in tribulations (Romans 5:8), and took pleasure in weaknesses (2 Corinthians 12:10). He is afraid that the Gentiles may lose heart, when they see him persecuted for helping them: they ought rather to glory in this.

Now he returns to Ephesians 3:1 after his magnificent digression, and at last gives in fulness the prayer for their enlightenment which he began Ephesians 1:17, It is a very bold intercession.

14-21. Prayer and doxology. 'May they have great spiritual power, may Christ dwell in their hearts, may they know His incomprehensible love, and be filled up to the measure of God's fulness. To Him, who can give in abundance blessings which we cannot even imagine, be glory for ever.'
