The false prophet is defined in Deuteronomy 13.
... If there will arise among you a prophet, or a dreamer of a dream, and he gives you a sign or a wonder, and the sign or the wonder of which he spoke to you happens, [and he] says, "Let us go after other gods which you have not known, and let us worship them," you shall not heed the words of that prophet, or that dreamer of a dream; for the Lord, your God, is testing you, to know whether you really love the Lord, your God, with all your heart and with all your soul.
So there are 3 criteria:
- Performs wonders
- Accurately predicts the future
- Promotes a god which "you have not known"
Each time that Jesus speaks about "my father", that is speaking about a god which the Jewish people do not know. It's blatently obvious for a Jewish person. The way we speak it would be "our father". Not "my father". When I read the gospels, this and other things were major red-flags. It's not that he didn't fulfill prophecy, it's that he is "off the path".
In addition to this, Jesus himself admits this.
John 8:
The Pharisees challenged him, “Here you are, appearing as your own witness; your testimony is not valid.”
Jesus answered, “Even if I testify on my own behalf, my testimony is valid, for I know where I came from and where I am going. But you have no idea where I come from or where I am going. You judge by human standards; I pass judgment on no one. But if I do judge, my decisions are true, because I am not alone. I stand with the Father, who sent me. In your own Law it is written that the testimony of two witnesses is true. I am one who testifies for myself; my other witness is the Father, who sent me.”
Then they asked him, “Where is your father?”
“You do not know me or my Father,” Jesus replied. “If you knew me, you would know my Father also.” He spoke these words while teaching in the temple courts near the place where the offerings were put. Yet no one seized him, because his hour had not yet come.
So, the law states a false prophet will say "Let us go after other gods which you have not known". And Jesus admits "You do not know me or my Father". That's it. The nail in the coffin. The smoking gun. He refers to his god as "my father" not "our father" repeatedly throughout the gospels, and says that this deity is unknown to the Jewish people. That is what a false prophet does.
Per Deuteronomy 13, these people are indeed sent from God, but as a test for the Jewish people. Christians of that time, and even today, are participating in the test.
Jesus does speak of His Father as the God of Abraham, Isaac and Jacob so in that respect Jesus is speaking of the same God as the Jews have, the God that your ancestors knew.
I would see other prophets who blatantly wanted said to follow other gods, the Baals etc, as being false prophets in that respect.
When Jesus was saying in John 8 and other places that the people He was speaking to did not know Him or His Father, He was speaking to specific people among the Jews and was judging them and was not saying that about the whole nation.
The fact is that Jesus did say that His God and Father was both Father of Himself and of His disciples and the Jewish nation but Jesus did seem to distinguish Himself as being God's Son in a special way, as you notice.
I also see this in the Hebrew scriptures concerning the Messiah even if you may not see the same passages as Messianic.
This first passage is about the one who inherits the nations and is given the ends of the earth as a possession.
Psalm 2:7 I will proclaim the Lord’s decree:
He said to me, “You are my son;
today I have become your father.
8 Ask me,
and I will make the nations your inheritance,
the ends of the earth your possession.
9 You will break them with a rod of iron;
you will dash them to pieces like pottery.”
10 Therefore, you kings, be wise;
be warned, you rulers of the earth.
11 Serve the Lord with fear
and celebrate his rule with trembling.
12 Kiss his son, or he will be angry
and your way will lead to your destruction,
for his wrath can flare up in a moment.
Blessed are all who take refuge in him.
I suppose there are plenty
This next one is about the horn (strength) of David, imo the Messiah, who specifically calls God "My Father".
He is appointed to be God's firstborn. (and presumably that means to rule the nations as the Son in Psalm 2 does)
Psalm 89:24 My faithful love will be with him,
and through my name his horn[
f] will be exalted.
25 I will set his hand over the sea,
his right hand over the rivers.
26 He will call out to me, ‘You are my Father,
my God, the Rock my Savior.’
27 And I will appoint him to be my firstborn,
the most exalted of the kings of the earth.
28 I will maintain my love to him forever,
and my covenant with him will never fail.
29 I will establish his line forever,
his throne as long as the heavens endure.
This Psalm goes on to say what will happen to this anointed one, what the Jews would do to Him, and the Psalmist wonders after that, how long will God be angry.
This is not about David, whose life was not cut off in his youth.
Psalm 89:38 But you have rejected, you have spurned,
you have been very angry with your anointed one.
39 You have renounced the covenant with your servant
and have defiled his crown in the dust.
40 You have broken through all his walls
and reduced his strongholds to ruins.
41 All who pass by have plundered him;
he has become the scorn of his neighbors.
42 You have exalted the right hand of his foes;
you have made all his enemies rejoice.
43 Indeed, you have turned back the edge of his sword
and have not supported him in battle.
44 You have put an end to his splendor
and cast his throne to the ground.
45 You have cut short the days of his youth;
you have covered him with a mantle of shame.
46 How long, Lord? Will you hide yourself forever?
How long will your wrath burn like fire?
The conclusion I draw is that Jesus God is the God of the Jews and He did not say to follow other Gods and that He is the Son of God in a special way, as the Hebrew Scriptures suggest.
