The knowledge of God is essential for life

God confirms many times that He is the only God

...also in the book of Isaiah: (examples)

Isaiah 37

16 O LORD of hosts, God of Israel, that dwells between the cherubim,
you are the God, even you alone, of all the kingdoms of the earth: you have made heaven and earth.

Isaiah 40

13 Who has directed the Spirit of the LORD, Or as His counselor has informed Him?

14 With whom did He consult and who gave Him understanding?
and who taught Him in the path of justice and taught Him knowledge
and informed Him of the way of understanding?

Isaiah 43 (NAS)

10 “You are My witnesses,” declares the LORD, “And My servant whom I have chosen,
So that you may know and believe Me and understand that I am He.
Before Me there was no God formed, and there will be none after Me.

11 “I, even I, am the LORD, and there is no savior besides Me.

12 “It is I who have declared and saved and proclaimed, and there was no strange god among you;
So you are My witnesses,” declares the LORD, “And I am God.

13 “Even from eternity I am He, And there is none who can deliver out of My hand; I act and who can reverse it?”

other unambiguous passages, absolute statements of God:

Isaiah 44:6, 24; 45:5-7, 12, 18, 21-23; 46:9, 10; 48:12, 13; 66:1, 2.

He who made the heavens and the earth is the same who will make the new heavens and the new earth:

Isaiah 66

22 “For just as the new heavens and the new earth Which I make will endure before Me,”
declares the LORD, “So your offspring and your name will endure.

The Son of God, the fulfillment of many promises

e.g. in

Psalms 2 MB30

7 “I will surely tell of the decree of the LORD:
He said to Me, ‘You are My Son, Today I have begotten You.

promised also in the book of Isaiah: (examples)

  • As Lord, LORD who speaks to Isaiah from the divine throne (from the future) (ch.6)
    (John gets the revelation on Patmos, in which he also hears sayings of the Lord on the Day of the Lord)
  • As a Child and as a Son with the name "father of eternity" on whom the rule rests (ch.9).
  • As Cyrus, the anointed one (ch.45)
  • As the glorified man in whom God will come again (ch.45, 23)
    (see also Rev.1, 4.5: Here it is also spoken of the Creator God (Who is, Who was, Who is to come)
    and Jesus Christ, the Son of Man, in whom He will come).
  • As God's holy arm, which He has uncovered
    and through whom His salvation is seen (Isaiah 52:10) M315
  • As the chosen, righteous servant of God,
    on Whom our punishment lay and Who will be highly exalted. (ch.53)
  • As the obedient God-hero (God-fighter, Israel) to whom God gave His word (ch.49,2),
    who returns after having carried out the whole will of God (ch.55, 10.11) M315
  • As Christ through whom God pours out His mercy on the grieving of Zion (ch.61)
  • As Judge and Redeemer (ch.63)

We read about the fulfillment of the promises in Luke 1 and 2, retrospectively in Hebrews 1:5 or in Matthew 3:17.
Every sonship begins at the earliest with the begetting, so also the sonship of the Son of God.
Temporally according to Matthew 3:17, God sent His Son into the world when He was about 30 years old. (Luke 3,23)
Of course the Son of God came out of heaven, but He was not yet Son then,
but – as the Word of God – the Creator‑God.
(see: The sending of the Word of God, announced in the Old Testament) MB30

What does the Son of God say about the knowledge of God?

After the 70 disciples whom the Lord Jesus sent out returned with joy, He rejoices a little later:

Luke 10 (NAS)

21 At that very time He rejoiced greatly in the Holy Spirit, and said,
“I praise You, O Father, Lord of heaven and earth,
that You have hidden these things from the wise and intelligent and have revealed them to infants.
Yes, Father, for this way was well-pleasing in Your sight.

22 All things have been handed over to Me by My Father,
and no one knows who the Son is except the Father,
and who the Father is except the Son, and anyone to whom the Son wills to reveal Him.

John 17

3 And this is life eternal, that they might know You the only true God,
and Jesus Christ, whom You have sent.

Whoever does not have this knowledge does not have eternal life!

John 10

30 I and my Father are one.

John 14

6 Jesus said unto him (Thomas), I am the way, the truth, and the life:
no man comes unto the Father, but by me.

7 If you had known me, you would have known my Father also:
and from henceforth you know him, and have seen him.

8 Philip said unto him, Lord, show us the Father, and it will satisfy us.

9 Jesus said unto him, Have I been so long a time with you, and yet have you not known me, Philip?
he that has seen me has seen the Father; and how say you then, Show us the Father?

10 Believe you not that I am in the Father, and the Father in me?
the words that I speak unto you I speak not of myself:
but the Father that dwells in me, He does the works.

11 Believe me that I am in the Father, and the Father in me:
or else believe me for the very works' sake.

Philip is rebuked. He has not (yet) recognized the Father in the Son.

John 20

28 And Thomas answered and said unto him, My Lord and my God.

29 Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed:
blessed are they that have not seen, and yet have believed.

Thomas' faith is confirmed, but only after he has seen.

Thomas recognized God the Father in the Son of God,
but only after he has seen Him with His stigmata in front of him (according to John 14:7).
Possibly Thomas also remembered Zechariah 12:10 or Isaiah 52:53.

1 Peter 1 M315

8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing,
ye rejoice with joy unspeakable and full of glory,

Matthew 3 (NAS)

17 and behold, a voice out of the heavens said,
“This is My beloved Son, in whom I am well-pleased.”

John 13 (NAS)

3 Jesus, knowing that the Father had given all things into His hands,
and that He had come forth from God and was going back to God,

Matthew 11 (NAS)

27 All things have been handed over to Me by My Father;
and no one knows the Son except the Father;
nor does anyone know the Father except the Son, and anyone to whom the Son wills to reveal Him.

Matthew 28 (NAS)

18 And Jesus came up and spoke to them, saying,
“All authority has been given to Me in heaven and on earth.

What is the Son of God thinking about in John 17:5


John 17

5 Now, Father, glorify Me together with Yourself,
with the glory which I had with You before the world was.

It is obvious that He thinks of what is written about Him and of the promises,
and the promises concerning Him, which He interpreted to His disciples and fulfilled Himself.

He knows that He came forth from within God. (John 1:18; 8:42)

See also: "The Son of God, the fulfillment of many promises".

In Him dwells the wisdom of God (Luke 2:40; James 3:17),
of which it is already written in Proverbs:

Proverbs 8 (LXX)

22 The LORD created me the head of his ways for His works.

23 Before the eon He founded me in the beginning,
before the making the earth;

24 and before the making the abysses;
before the coming forth of the springs of waters;

25 before the seating of the mountains;
and before all the hills He engenders me.

26 The LORD made regions and uninhabited places,
and uttermost parts of the inhabitable world under the heavens.

27 When He prepared the heaven, I was present with Him;
even when He seperated His throne upon the winds,

28 when He made the upward clouds strong,
and as made the springs under heaven safe,

29 in putting of his restriction to the sea, and the waters shall not go by His mouth,
and as He made the foundations of the earth strong,

30 I was by Him. I was being in accord in which he rejoiced with.
And each day I was glad in front of Him at all time;

31 even when He was pleased with the completing the inhabitable world,
and was pleased in the sons of men.

The Son of God recognizes that He as the arm of God,
has carried out the saving works of God, or is about to do the most hard:

Deuteronomy 26

8 and the LORD brought us out of Egypt with a mighty hand and an outstretched arm
and with great terror and with signs and wonders;

Isaiah 52

10 The LORD has bared His holy arm In the sight of all the nations,
That all the ends of the earth may see The salvation of our God.

Reflection and conclusions

1 Timothy 3

16 And without doubt great is the mystery of godliness:
God5 was manifest in the flesh,
justified in the Spirit,
seen of angels (messengers),
preached unto the Gentiles,
believed on in the world,
received up into glory.

5 Here the Greek says θεός (God) and again not Son or He.

John 1

18 No man has seen God at any time; the only begotten Son,
who is in the bosom chest of the Father, he has declared him.

2 Corinthians 5 M315

18 Now all these is from God, who reconciled us to Himself through Christ
and gave us the ministry of reconciliation,

19 namely, that God was in Christ reconciling the world to Himself,
not counting their trespasses against them,
and He has committed to us the word of reconciliation.

Colossians 1

19 For it pleased the Father that in him should all fullness dwell;

20 And, having made peace through the blood of his cross,
by him to reconcile all things unto himself; by him,
I say, whether they be things in earth, or things in heaven.

Colossians 2

9 For in Him dwells all the fullness of the Deity bodily.

God, Jesus, the Creator of heaven and earth and all life, was revealed in the flesh,
in the man Jesus Christ, who inherited the name of the Father.

The man Jesus Christ is called the Son of God
because God begat Him out of Himself (Luke 1:35; Heb. 1:5).
He came forth from out of God,
the Firstborn from above, who has the preeminence in everything (Col 1:18).

When the Son of God was about 30 years old, God the Father sent Him into the inhabited world (Jn 20:21).
 Beginning of the Good News in all the Gospels. (see also Gal 4:4; Mk 1:14, 15) M315

God loves His Son above all things, whom He has known since before the foundation of the world,
for whose sake He made the whole creation and for Him He made the creation.
The Son of God has always done what is pleasing to God and has given His life to take it again.
(John 8:29; 10:17; Heb. 10:7-9).

The man Jesus was also the last Adam, and He became a life-giving Spirit (1 Cor 15:45).
The Word of God, is the life-giving Spirit (John 6:63),
the divine seed (1 Pet 1:23) and the living bread that came out of heaven (Jn 6:48, 51) MB30
Through the Word of God people come to faith (e.g. Acts 10:44) M315

To all who receive Him because they believe in His name,
He gives the power to become children of God. (Jn 1:12)

He is the Lamb of God who takes away the sin of the world. (Jn 1:29).
He has exalted the name of God, Jesus, above all things.
He will judge the living and the dead as the Lamb of God.
Wonderful, adorable Lord!

The Son of God is omnipotent, because God, the Father, has given Him the whole creation
and all power in heaven and on earth. (Mt 28.18; Jn 13.3)

God, who is and who was and who is to come (Rev 1,4) will come again in Jesus Christ,
in His beloved Son, our Lord, as the King of Kings and Lord of Lords,
whom He will again introduce into the inhabited world (Heb 1:6ff).
The only true Creator God fully identifies with His Son: (Isa 24:23; 52:7).
The Lamb of God is Lord of Lords and King of Kings (Rev 17,14).

God speaks of His Son as God when He will reintroduce Him into the inhabited world:
(Hebrews 1:8) M315

After God has subjected everything to His Son, the Son will also be subjected to His God and Father.
1 Corinthians 15:28 M315

By the Spirit of Christ guiding us into all truth,
we may grow in the knowledge of God and His Son,
until we may (finally) see Him. (2 Peter 3:18)

Jeremiah 9 M315

23 Thus says the LORD, “Let not a wise man boast of his wisdom,
and let not the mighty man boast of his might, let not a rich man boast of his riches;

24 but let him who boasts boast of this, that he understands and knows Me,
that I am the LORD who exercises lovingkindness, justice and righteousness on earth;
for I delight in these things,” declares the LORD.

1 Corinthians 1 M315

31 so that, just as it is written, “Let him who boasts, boast in the Lord.“

1 John 4

19 We love him, because he first loved us.
