The Bible doesn't mention the Trinity, describe it, or explain it. The doctrine itself wasn't invented until around the 4th century when it was sanctioned as the official position of the church by emperor Constantine.
Matthew 28:19-20 NIV
"Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you."
John 14:15-21 NIV
“If you love me, keep my commands. And I will ask the Father, and he will give you another advocate to help you and be with you forever-the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you. I will not leave you as orphans; I will come to you. Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. On that day you will realize that I am in my Father, and you are in me, and I am in you. Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.”
In the Bible, Jesus isn't God.
Matthew 1:23 NIV
"The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”)."
John 1:1-14 NIV
"In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.
There was a man sent from God whose name was John. He came as a witness to testify concerning that light, so that through him all might believe. He himself was not the light; he came only as a witness to the light.
The true light that gives light to everyone was coming into the world. He was in the world, and though the world was made through him, the world did not recognize him. He came to that which was his own, but his own did not receive him. Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— children born not of natural descent, nor of human decision or a husband’s will, but born of God.
The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth."
He's a man with a God just like the disciples were men with a God. They were all anointed with power and authority to forgive sins, heal the sick, raise the dead, cast out demons, etc. There isn't anything Jesus did that the other disciples couldn't do
John 15:5 NIV
"I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing."
. Nothing demonstrates the deity of Jesus in the Bible. Jesus even denied being God and no one apparently believed he was God.
Exodus 3:13-14
"Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?”
God said to Moses, “I am who I am. This is what you are to say to the Israelites: ‘I am has sent me to you.’”
John 8:54-59 NIV
"Jesus replied, “If I glorify myself, my glory means nothing. My Father, whom you claim as your God, is the one who glorifies me. Though you do not know him, I know him. If I said I did not, I would be a liar like you, but I do know him and obey his word. Your father Abraham rejoiced at the thought of seeing my day; he saw it and was glad.”
“You are not yet fifty years old,” they said to him, “and you have seen Abraham!”
"Very truly I tell you,” Jesus answered, “before Abraham was born, I am!” At this, they picked up stones to stone him, but Jesus hid himself, slipping away from the temple grounds."
John 10:30-38 NIV
"I and the Father are one.”
Again his Jewish opponents picked up stones to stone him, but Jesus said to them, “I have shown you many good works from the Father. For which of these do you stone me?”
"We are not stoning you for any good work,” they replied, “but for blasphemy, because you, a mere man, claim to be God.”
Jesus answered them, “Is it not written in your Law, ‘I have said you are “gods”’? If he called them ‘gods,’ to whom the word of God came—and Scripture cannot be set aside— what about the one whom the Father set apart as his very own and sent into the world? Why then do you accuse me of blasphemy because I said, ‘I am God’s Son’? Do not believe me unless I do the works of my Father. But if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me, and I in the Father.”
In Jesus' teachings, he taught them to only pray to the Father,
Acts 7:59-60 NIV
"They went on stoning Stephen as he called on the Lord and said, "Lord Jesus, receive my spirit!" Then he fell on his knees and cried out with a loud voice, “Lord, do not hold this sin against them!” Having said this, he fell asleep."
Matthew 2:9-11 NIV
"After they had heard the king, they went on their way, and the star they had seen when it rose went ahead of them until it stopped over the place where the child was. When they saw the star, they were overjoyed. On coming to the house, they saw the child with his mother Mary, and they bowed down and worshiped him. Then they opened their treasures and presented him with gifts of gold, frankincense and myrrh."
Matthew 21:8-9 NIV
"A very large crowd spread their cloaks on the road, while others cut branches from the trees and spread them on the road. The crowds that went ahead of him and those that followed shouted,
“Hosanna to the Son of David!”
“Blessed is he who comes in the name of the Lord!”
“Hosanna in the highest heaven!”
Phillipians 2:5-11 NIV
"In your relationships with one another, have the same mindset as Christ Jesus:
Who, being in very nature God,
did not consider equality with God something to be used to his own advantage;
rather, he made himself nothing
by taking the very nature of a servant,
being made in human likeness.
And being found in appearance as a man,
he humbled himself
by becoming obedient to death—
even death on a cross!
Therefore God exalted him to the highest place
and gave him the name that is above every name,
that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father."
