People who don't believe that Jesus is The Father, or believe that God is 2 or 3 beings/persons, point to the verses in the bible where Jesus and The Father interacted.
Revelation 4:8 to 5:10 The Father giving Jesus the seals, etc.
Genesis 1:26-27 Let us make man in our image/character.
Notice that verse 27 says "He", not "they". This shows that the "us" and "our" in verse 26 is not referring to 2 persons/beings. But rather, refers to 2 manifestations of God. The Father and The Word/Logos.
Genesis 11:7-8 Let us go down and confuse the languages.
Notice in verse 8, The Lord does it. Not "they". Not "the Lords".
Again this shows one God that is only one being/person.
Here are additional verses to prove that God is One: (Not 2, not 3.)
Psalms 16:10 "Holy One"
Psalms 71:22 "Holy One"
Psalms 89:18 "Holy One"
Isaiah 10:20 "Holy One"
43:11 I am Theos and beside me there is no Saviour.
45:23 To me shall every knee bow, every tongue confess! (Philippians 2:10-11)
Acts 2:27 "Holy One"
4:12 No salvation by anyone else.
13:34-35 "Holy One"
Mark 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord.
Deuteronomy 6:4 Hear, O Israel: The LORD our God is one LORD.
It never says that God is two.
The only place where it talks about 3:
Matthew 28:19 which was quoted much differently in the early centuries, thereby proving that the trinity was added.
And 1 John 5:6-8 where the trinity did not originally appear in the early bible manuscripts, but was added later.
Luke 10:18 "And He said unto them, I beheld Satan as lightning fall from heaven".
John 14:6-9 Show us The Father! Here I am!
Philippians 2:5-11 Jesus considered himself to be equal to God The Father. Every tongue, knee from Isa. 45:23
1 Tim. 3:16 God in the flesh. Not a god in the flesh.
Zechariah 14:3-5 "The Lord my God" coming.
Here's the reason for the confusion and the answer to their questions/concerns:
Before the creation of mankind, God divided himself into 2 manifestations. One of those, is called The Logos (The Word). It's the part of God that came to Earth and died and rose again. But The Word always existed and was The Father.
But realized that He needed a vessel/robe to be able to relate with humans, to speak to them, appear to them without killing them with his tremendous power. And such vessel was also needed to eventually save them having perfectly planned it all.
1 Corinthians 15 says that after death is totally defeated (when paradise comes after the Great White Throne Judgment), then God shall be "all in all", which would more correctly be translated as "become whole again."
After we enter paradise (new heavens new earth), we'll no longer see 2 manifestations. Only one. Because there will no longer need to be a intercession between man and God, because there will no longer be human flesh/vessels.
The key is 1 Corinthians 15:22-28
shall become whole.
This shows that He divided himself into 2 manifestations. But He is still one being.
Last night, after I had already finished the sermon notes, and after having already determined that 1 Corinthians 15 is the key verse of revelation, I saw on Facebook, that someone had posted “The gospel that saves… in 2 parts”! And also in the same post, the first and main/key verse in the post was in 1 Corinthians 15. (Not exactly the same verse. But I could not see the verse number in the post until this morning after clicking on it. But the fact that I saw “1 Corinthians 15” last night in the same post as “2 parts” and not “2 beings”, is a huge, amazing confirmation!) I also saw Isaiah 45:23 last night after I had finished the sermon notes, and had to get up out of bed to add it to the notes. This is Jesus giving me the verses for the sermon.
