Ephesians 1:17

Effective PrayerThe Spirit of wisdom and revelation, i.e. "information" in order that they "may know God the Father better." That "the eyes of your heart" (a euphemism for ones "mind") may be "enlightened", i.e. "information" in order that they "may know the hope" of their calling and how rich their inheritance is.That they "may know" of "His incomparably great power" exercised for believers.

"It is not salvation merely that we have received; but we are set here as saved ones to grow in grace and in the knowledge of our Lord Jesus, in mind and ways of Him by whom we live. Hence there are little children, young men, and fathers (1 John 2), showing the grades, not of salvation, but of growth in the divine life."
