Trinity: A Few verses of Explanation of the Trinity +

What Is The Trinity?

The Trinity is the belief that God is one being, three persons: The Father, Son, and Holy Spirit.  It may not make sense according to what you see in your daily world, but it is quite consistent with what the Bible says.

While there are some alternative doctrines, the trinity is the view that is presented to Muslims by scholarly Christian apologists.  I am not aware of any exceptions.

I somewhat reluctantly concluded that the traditional view is the best.  The argument that persuaded me was this:
If Jesus were just human of some kind, then that would mean that the hard work of paying for our salvation was done by a person, and not God.  Who then do you want to worship?  With the Trinity, God gets the worship he deserves.

You can expect to be asked about the trinity when talking to Muslims, but you don't have to be an expert.  Usually, if you can intelligently answer few questions the conversation turns to something else.

Muslims typically have the expectation that the Trinity is something that was invented later, like in the council of Nicea, or that it is part of a corruption of the Bible.

These verses show that Jesus pre-existed creation.

In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made through him. Without him was not anything made that has been made
...

The Word became flesh, and lived among us.
--John 1:1-3, 14

John introduces this as his thesis for the entire Gospel of John and it which concludes like this:

These are written, that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name.
--John 20:31


Now, Father, glorify me with your own self with the glory which I had with you before the world existed.
--John 17:5

Have this in your mind, which was also in Christ Jesus, who, existing in the form of God, didn’t consider equality with God a thing to be grasped, but emptied himself, taking the form of a servant, being made in the likeness of men.  And being found in human form, he humbled himself, becoming obedient to death, yes, the death of the cross. Therefore God also highly exalted him, and gave to him the name which is above every name; that at the name of Jesus every knee should bow, of those in heaven, those on earth, and those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
--Phil 2:5-11

Hebrews 1:1-14 (the entire chapter) is about who Jesus is.

From Jesus in Revelation, we have these:

I am the Alpha and the Omega, says the Lord God, who is, and who was, and who is to come, the Almighty.
--Revelation 1:8

 I am the first and the last, and the living One; and I was dead, and behold, I am alive forevermore.
--Revelation 1:17

 I am the Alpha and Omega, the First and the Last, the Beginning and the End.
--Revelation 22:13

Note: When it is convenient, Muslims insist on accepting only the words of Jesus himself.  However, the Quran is not held to this standard.
