Charles Ellicott Commentary Ephesians 1:19

"and what the exceeding greatness of his power to us-ward who believe, according to that working of the strength of his might" — Ephesians 1:19 (ASV)

According to the working of his mighty power.—More correctly, the working of the might of His strength. The word “power” is a general word for force, which may be latent and, in fact, often describes force which is latent, in contrast to the word used here for working or energy.

St. Paul, therefore, adds that this power of God is not latent; it actually works “according to,” that is, up to the full measure of “the might of the strength” of God—of that strength which is a part of His nature.

The whole phrase forms a glorious climax, in which the Apostle accumulates words ever stronger and stronger to approach the description of the omnipotence of the Spirit. It is a “force of exceeding greatness”; it is an ever energetic force; its only measure is the immeasurable might of the divine nature. (Philippians 3:21; Colossians 1:29; Colossians 2:12).
