That all things of the Father are His (Matt. 11:27; John
16:15; 17:2).

And that He hath all power in heaven and on earth (Matt.
28:18).

He says "in heaven and on earth," because He that rules heaven rules the earth also, for the one depends upon the other.{1} "Ruling heaven and earth" means to receive from the Lord every good pertaining to love and every truth pertaining to faith, thus all intelligence and wisdom, and in consequence all happiness, in a word, eternal life. This also the Lord taught when He said:

He that believeth on the Son hath eternal life; but he that believeth not the Son shall not see life (John 3:36).

Again:

I am the resurrection and the life; he that believeth on Me, though he die yet shall he live; and whosoever liveth and believeth on Me shall never die (John 11:26, 26).

And again:

I am the way, the truth, and the life (John 14:6).

{Footnote 1} The entire heaven is the Lord's (n. 2751, 7086). He has all power in the heavens and on the earths (n. 1607, 10089, 10827). As the Lord rules heaven He rules also all things that depend thereon, thus all things in the world (n. 2026, 2027, 4523, 4524). The Lord alone has power to remove the hells, to withhold from evil and hold in good, and thus to save (n. 10019).

6. There were certain spirits who while living in the world had professed to believe in the Father; but of the Lord they had the same idea as of any other man, and therefore did not believe Him to be the God of heaven. For this reason they were permitted to wander about and inquire wherever they wished whether there were any other heaven than the heaven of the Lord. They searched for several days, but nowhere found any. These were such as place the happiness of heaven in glory and dominion; and as they were unable to get what they desired, and were told that heaven does not consist in such things, they became indignant, and wished for a heaven where they could lord it over others and be eminent in glory like that in the world.
