They Who Kneel Before God Can Stand Before Anyone.
For this reason I bow my knees to the Father of our Lord Jesus Christ. Ephesians 3:14 NKJV
We now come to the second part of this chapter, which contains Paul's devout and affectionate prayer to God for his beloved Ephesians.--For this cause. This may be referred either to the immediately Ephesians 3:13, That you faint not..., or, rather, the apostle is here resuming what he began at the Ephesians 3:1, from which he digressed in those which are interposed. Observe,
To whom he prays--to God, as the Father of our Lord Jesus Christ, of which see Ephesians 1:3.
His outward posture in prayer, which was humble and reverent: I bow my knees. Note, When we draw nigh to God, we should reverence him in our hearts, and express our reverence in the most suitable and becoming behaviour and gesture. - Matthew Henry
