Being as you are bringing this up. I don't care much for your inference that Jesus was merely the God of Israel. No, like it was pointed out by the Samaritan woman: He is the God of the whole world. His ministry was directed at Israel but He actually created and OWNS the entire world and everything in it.
My deepest apology for using the terminology "God of Israel". I have found in Ephesians 2:19 the household of God
and Galatians_6:10 household of faith. Do either of these appeal more to you?
I don't believe Jesus OWNS the entire world and everything in it, yet. When Satan offered Jesus all the kingdoms of the world, Jesus did not correct Satan. Satan is at present still the legal owner of this world as Satan took it from Adam. Jesus came (one of many reasons) to take back this world and then after he has put all under Him, hand it over to the Father.
Mat_4:8 Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; 9 And saith unto him, All these things will I give thee, if thou wilt fall down and worship me.
Luk_4:5 And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time.
6 And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it. 7 If thou therefore wilt worship me, all shall be thine.
Isa_45:7 I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
Rev_11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
Rev_12:10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
Rev_17:17 For God hath put in their hearts to fulfil his will, and to agree, and give their kingdom unto the beast, until the words of God shall be fulfilled.
1 Corinthians 15:24-28 24Then the end will come, when he
hands over the kingdom to God
the Father after he has destroyed all dominion, authority and power. 25For he must reign until he has put all his enemies under his feet. 26The last enemy to be destroyed is death. 27For he "has put everything under his feet." Now when it says that "everything" has been put under him, it is clear that this does not include God himself, who put everything under Christ. 28When he has done this, then the Son himself will be made subject to him who put everything under him, so that God may be all in all.
