Where do you find the Trinity of God in the Bible?

Skeptics of the doctrine the Trinity often point to the fact that the word “Trinity” does not appear anywhere in scripture. Further ‘evidence,’ they say, that the doctrine is merely man-made. They are correct that the term does not appear in scripture, but neither do the words omniscient, omnipotent, or omnipresent appear. These words, and the word ‘Trinity,’ are words created for convenience to capsulate a doctrine found throughout the Word of God.
Do you believe God is all-knowing? That is omniscience (omni = all + science = knowledge). Do you believe God is all-powerful? That is omnipotence (omni = all + potent = power). Do you believe God is present everywhere? That is omnipresence (omni = all + present = in that place). Likewise ‘Trinity’ is a man-made word capsulizing the truth that God is tri-une (tri = three + unity = one), three Persons, one God. ‘Universe’ is a similarly constructed word (unity = one + diversity = many different), one system, many varied components.
So, where in scripture do we find thus tri-unity of God indicated? Here are some examples…
Jesus’ baptism: Voice of the Father, Son baptized, Spirit descending like a dove.
“As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and alighting on him. And a voice from heaven said, ‘This is my Son, whom I love; with him I am well pleased.’” (Matt. 3:16-17).
Salvation: Chosen by the Father, sanctified by the Spirit, sprinkled with the blood of Jesus.
“…who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, to be obedient to Jesus Christ and sprinkled with his blood“ (1 Pet. 1:2).
Sanctification: Grace of the Lord Jesus, love of God, fellowship of the Holy Spirit.
“May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all. “ (2 Cor. 13:14).
Baptism: Baptized in one name, yet three Persons—Father, Son, and Holy Spirit.
“…go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit“ (Matt. 28:19).
Prayer: Strengthened by his Spirit, know the love of Christ, filled with fullness of God.
“…I kneel before the Father, … strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith.“ (Eph. 3:14-17).
Christian Growth: Chosen by God, loved by the Lord, sanctified by the Spirit.
“But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits to be saved through the sanctifying work of the Spirit and through belief in the truth.“ (2 Thess. 2:13).
Add to this the many scriptures which state there is only one God…
For e.g.
“To you it was shown that you might know that the Lord, He is God; there is no other besides Him.” (Deut. 4:35).
“Hear, O Israel! The Lord is our God, the Lord is one!” (Deut. 6:4).
“For there is one God, and one mediator also between God and men, the man Christ Jesus” (1 Tim. 2:5).
“You believe that God is one. You do well; the demons also believe, and shudder.” (James 2:19).
…and we understand that God is ONE God, eternally existent in THREE Persons.
