TWO DUTIES PRESSED UPON THOSE, WHO, UPON TRIAL, FIND THIS GRACE OF HOPE IN THEM. For exhortation ; and this either respects believers, who are furnished with this helmet ; or unbelievers, who yet are without hope. First, For you, believers, who, upon trial, are found to have this helmet of hope. Several duties are to be pressed vipon you as such. Section I.

Commenting on Ephesians 6:10-20

William Burkitt Anglican

Observe here, 1. The work which the heart of the apostle was set upon, and that is, the work of blessing God: we bless God one way, he blesses us another; he blesses us imperatoriously, by commanding his blessings upon us; we bless him optatively, when with thankful hearts we praise him, when we wish well to him, and speak well of him.

Albert Barnes Presbyterian

Verse 3. Blessed by the God and Father of our Lord Jesus Christ. This commences a sentence which continues to the close of Verse 12. The length of the periods in the writings of Paul, is one cause of the obscurity of his style, and renders an explanation often difficult. The meaning of this phrase is, that God has laid a foundation for gratitude for what he has done.
