“Praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints” (Ephesians 6:18).
Paul has just completed his description of the Christian’s armor when he goes directly into this beautiful expression of his actions on behalf of all fellow saints. He prays for them, and he is intense in doing so.
“Perseverance” means “persistence in doing something despite difficulty or delay in achieving success.” It comes from “persevere,” which means to “continue in a course of action even in the face of difficulty.” He remains steadfast in his prayers for his fellows.
Our determination in our prayers as well as in our worship and in our diligence in living for Christ should be obvious and enduring—we do not “faint,” “grow weary in well doing,” nor allow ourselves to become discouraged in our commitment. Rather, we remain constant and steadfast.
