The Scripture speaks in many places about the will of God; how He worketh His will; He doeth His will, etc. & etc. But there are three places in Scripture where He uses the term “His own will.”

This does not change the will of God, nor does it add to it or diminish it whatsoever. It does, however give us a sort of distinction to these three things under consideration, and the importance of them in His work of the eternal salvation of His elect.

Eph. 1:11, “In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:”

Let us remember that the “whom” under consideration is Christ; and that we are predestinated to an eternal inheritance, after the counsel of God's own will; which tells me that God personally attended to the eternal salvation of them “whom He did foreknow.” Rom. 8:29 We should give earnest heed because: Heb. 2:4, “God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?” Please read Heb. 2:1-4

Jas. 1:18 Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures. Still wondering? God the Father laid it out Himself, and God the Son came down from Heaven Himself and performed it.
