5. Those who are of the church cannot doubt that the Lord is the God
of heaven, for He Himself taught,

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).
