Christians acknowledge that all authority has been given to Jesus, at Matt 28:18 Jesus states this fact! Why do they ignore 1 Co 15:24-28?

We must have the mind of Christ, in order to be a Christian.

Notice what Christ believed.

(Romans 15:5, 6) “5 Now may the God who supplies endurance and comfort grant you to have among yourselves the same mental attitude that Christ Jesus had, 6 so that unitedly you may with one voice glorify the God and Father of our Lord Jesus Christ.”

What was Christ mind set?

That we all glorify his God and Father.

Why trinitarians reject this teaching is because it disproves their primary belief.

If they accept these verses, then they would have to humbly admit they were wrong.

If they humbly admit they were wrong, they would also have to admit Jehovah's Witnesses were correct.

Both of these ideas go against their prideful attitudes, which is the attitude the scribes and pharisees had toward Jesus, causing them to reject the simple truth as stated by Peter:

(Matthew 16:15-17) “15 He said to them: “You, though, who do you say I am?” 16 Simon Peter answered: “You are the Christ, the Son of the living God.” 17 In response Jesus said to him: “Happy you are, Simon son of Joʹnah, because flesh and blood did not reveal it to you, but my Father in the heavens did.”

Because they reject this truth, they refuse to pray to the God and Father of our Lord Jesus Christ from wisdom and understanding of him.

(Ephesians 1:3) “3 Praised be the God and Father of our Lord Jesus Christ, for he has blessed us with every spiritual blessing in the heavenly places in union with Christ, . . . 16 in my prayers, 17 that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and of revelation in the accurate knowledge of him. ” 

Without Jehovah's spirit of wisdom, one cannot come to know Jehovah the only true God.

Those scriptures are in plain English, only ignorant minds reason differently! At Matthew 28 Jesus says all authority has been given to him and if Jesus is Jehovah incarnate this statement made by Jesus himself would be a lie! And if Jesus is Jehovah incarnate there is no need for him to give back this authority to his Father and then subject himself to his Father as 1 Corinthians 15 says! 

This is so plain a first grader learning English would understand it! Why doesn't 99% of the Christian population believe that Jesus is God! The scriptures give us the answer! (2 Timothy 4:3, 4) For there will be a period of time when they will not put up with the wholesome teaching, but according to their own desires, they will surround themselves with teachers to have their ears tickled. 4 They will turn away from listening to the truth and give attention to false stories.

Eve was a perfect woman yet she was deceived by Satan the Devil, today Satan has little problem deceiving mankind. At John 5:19 we see the whole world is under the power of the evil one. This is why every government rules by man will fail! 

(Luke 4:5-6) 5 And the devil took him up, and showed him all the kingdoms of the world in a moment of time, 6 and said to him, "To you I will give all this authority and their glory; for it has been delivered to me, and I give it to whom I will.

It is a known fact that pagan cultures have influenced the Christian belief, again this is the work of Satan! Why does that reads Matt 28 and 1 Corinthians 15 turn a blid mind to what is written? (A) (Matt 13:19) When anyone heareth the word of the kingdom, and understandeth it not, then cometh the evil one, and snatcheth away that which hath been sown in his heart. This is he that was sown by the way side.

They have been brainwashed by Satan using his advocates, the  clergy of Christendom! (2 Timothy 4:3, 4) For there will be a period of time when they will not put up with the wholesome teaching, but according to their own desires, they will surround themselves with teachers to have their ears tickled. 4 They will turn away from listening to the truth and give attention to false stories. 

Satan is called the great bird catcher because he can blind peoples minds 

(2 Corinthians 4:3, 4) If, in fact, the good news we declare is veiled, it is veiled among those who are perishing, 4 among whom the god of this system of things has blinded the minds of the unbelievers, so that the illumination of the glorious good news about the Christ, who is the image of God, might not shine through.

This is why there is a great preaching work going on today, it is done by a group of people that Satan has used his advocates the clergy to blacklist them because Satan does not want anyone to know the truth! That does not stop this group from completing the commandment to preach the good news (Matthew 24:14) And this good news of the Kingdom will be preached in all the inhabited earth for a witness to all the nations, and then the end will come.

The false clergy has said we preach gloom and doom for mankind and this world we live in but the bible says it's good news! This is because in truth we preach the resurrection of the dead (Romans 6:7; Acts 24:15) and not hellfire and eternal torment in a burning hell! Immortal soul and a place of torment is a pagan belief and it is "not in the bible!" 

So what is this end that is coming? (John 12:31) Now there is a judging of this world; now the ruler of this world will be cast out.

Where is Satan cast out to (Rev 20: 10, 14) 10  and the devil who had deceived them was thrown into the lake of fire and sulphur where the beast and the false prophet were, and they will be tormented day and night for ever and ever. Now and interesting point is the devil and two (2) symbolic symbols are cast into the lake of fire! How are symbols tormented forever, with research we find being tormented in bible times was to be put in stocks, confined, unable to move! This make more sense when you read verse 14 of that same chapter (Rev 20:14) 14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire; Other bibles say hell or grave, no matter what we are talking about something that happens to the living, "death," and a place, "hell-hades-grave." So the devil, symbols, death, and hell are cast into the lake fo fire, verse 14 ends with "this is the second death" The lake of fire is the second death from where no resurrection will happen, dead forever! This is why Rev 21:3-4 says: 3 And I heard a great voice out of the throne saying, Behold, the tabernacle of God is with men, and he shall dwell with them, and they shall be his peoples, and God himself shall be with them, and be their God: 4 and he shall wipe away every tear from their eyes; and death shall be no more; neither shall there be mourning, nor crying, nor pain, any more: the first things are passed away.

Verse 4 says no more dying, why, because death has been cast into the lake of fire! Also with no one dying, there is no need of the grave (hell) it too has been cast into the lake of fire, The second death symbol is the lake of fire!

The bible has another symbol that is important to anyone who believes in God, its Babylon the Great, the mother of harlots! (prostitutes) Any false belief is part of Babylon the Great and this is what Rev 18:4 says about those that are in any false belief! (Revelation 18:4) And I heard another voice out of heaven say: “Get out of her, my people, if you do not want to share with her in her sins, and if you do not want to receive part of her plagues.

(2 Corinthians 6:17) “‘Therefore, get out from among them, and separate yourselves,’ says Jehovah, ‘and quit touching the unclean thing’”; “‘and I will take you in.’”

The true God Jehovah says all false beliefs are unclean!

For those searching for truth Matt @8:18 and 1 Corinthians 15:24-28 will have an impact and spark interest if so it means the true God reads you have a sheeplike heart, if not then you may be the goats Jesus rejects when he separates at the time of the end! 

(1 Corinthians 3:6) I planted, A·polʹlos watered, but God kept making it grow,

Amazing claim of omniscience you are making that you know the heart of all Christians.

well, the traditions of Islam refute many biblical doctrines as being "altered" and false. in fact they are taught to believe the gospel of Barnabus which says there is no resurrection of Jesus. therefore, as being taught that the Koran has Higher authority than the bible There is no authority of Jesus as being a God. Neither is he a Son of God because God has children, and one cannot believe in the spirit of Adoption because the Messenger of Allah has spoken it. these are 3 false doctrines that Koran teaches. that the bible claims to be the truth. of course because they also teachh that Paul is a false apostle. they will not believe any of the epistles of Paul. and even then Bart Erhman and several other scholars proclaim that half of the epistles of Paul are forgeries. so ! claiming that any words of Paul is authoritative, (which i disagree with) is telling all muslims that christians are liars and teach lies.

now, as i believe i have been given DIRECT "personal" revelation of the Restored Church, (i.e not to be confused with the reformed-churches) i believe all christianity is in a state of Apostasy as well as the Jews and all Islam and even all Hinduism. i do believe the bible new testament and these verses are True !

How do they ignore it?  Please provide an example.

Yes indeed, Jesus' authority will be relinquished as 1 Cor. 15 predicts, Isaiah 46:10, Eph. 3:10-11.

There is nothing Jesus had that we don't. We all have the Christ mind.

You have wrong assumptions...GOD IS IN 3 FORMS..
