I've heard a lot of discussion lately about whether Jesus is God, or not. I know there are arguments for Trinity, and arguments against. But I am wondering, why is it so important for those who believe in Trinity that Jesus is also God, and not only a perfect human being?
The main reason that it is important to Protestants, that Jesus is the son of God, is because that is the basic precept on which their salvation depends. If Jesus were not deity, (or God) he could not keep the promises he made concerning salvation.
All Scripture is quoted from the King James translation.
In the above passage what you will find, is that Jesus has promised that he will give salvation to his sheep. Jesus used the example of a shepherd because the people were familiar with sheep herding, and he also referred to those being saved as his sheep.
But the really important part is the part about his laying down his life and being able to take it up again.
If Jesus did not have the power to take up his own life again, how would he ever have the ability to give eternal life to anyone else?
Unless Jesus were God and not just a good man all of these would be hollow promises, since salvation is of God:
The veracity of Jesus claim is found in the Old Testament. Particularly in the Book of Isaiah, which is most descriptive, and also in many other Prophets from many years before his birth, which is foretold in Isaiah chapter 7:
Finally; if Jesus were not God all who have put their trust in Jesus for their Salvation would still be lost with no hope of eternal life.
Mark 2:17 When Jesus heard [it], he saith unto them, They that are whole have no need of the physician, but they that are sick: I came not to call the righteous, but sinners to repentance.
Luke 19:10 For the Son of man is come to seek and to save that which was lost.
Jesus' divinity is not strictly a protestant assertion: The Blessed Trinity (Roman Catholic).
Jesus' divinity is crucial to his message. He made such assertions, and if we are to trust anything he says, then everything he says must be true. Similarly, if we are to trust anything the Biblical authors said, we must trust all of it.
The essential message of salvation is that God himself became human and paid the price for our sins. Had God just chosen some good person to die, it would not have been the same kind of personal sacrifice on God’s part. Not only that, but only a perfect sacrifice would do it, and nobody but God himself could have been perfect (Ro 3:23, 1 John 1:8).
It is important for anyone that believes the account of Jesus. He said that He is the Son of God.
He also said that He is one with the Father (God).

Why is it important for people who believe in Trinity that Jesus is God?
First, because people who believed in the Trinity did not believe it through reading it into the texts of the Scriptures but rather, the Scriptures itself forcefully evinces the fact of an eternal Triad. Without the Trinity, there is no God revealing himself to mankind and this entails the importance of Jesus' deity.
Second, because if Jesus wasn't God as the Father is God, then, it means that the Trinity isn't true and this entails that God did not save mankind whereas God alone could save.We don't even have any options because if Jesus wasn't God but only human by nature, then, it means that Jesus is sinful like the rest of us for Jesus cannot be other than our nature and hence, Jesus couldn't save.
In order to solve this dilemma, we must accept the Biblical teaching of the Trinity because it is important that Jesus is God or else, God did not provide salvific grace.
Mankind is unable to save themselves because all are of Adam and bears the consequence of the original sin ( Romans 5:12-21).
The only solution for mankind's problem is to obey all of God's law without fail or else, he would end up experiencing God's wrath ( Ephesians 2:3).
But the New Testament records that the Law was given for the purpose of knowing that no one is able to save themselves but rather, if there is such salvation available, it is only by God's grace which is the case in the NT ( Romans 3:20).
There are three options to be used for saving mankind:
1) God 2) Angels 3) Humans
Option no. 1 is a "yes" because God alone can give grace of forgiveness and new life for he was the recipient of the human transgression ( Ephesians 1:6).
Option no 2 is a "no" because Angels are neither giver of grace nor affected by mankinds' condition.
Option no. 3 is a "yes" because mankind needs to pay for its sin but the problem is that mankind is unable ( Matthew 19:25-26).
Only God is able to save mankind from its terrible condition because neither angels nor mankind is able.But we have another problem, God is not man and only man can pay for his sins.In order for God to forgive mankind and be reconciled to him, humans must pay the price of his sins and not God for God wasn't the one who sinned.This problem is solved in the Incarnation of our Lord Jesus.
God's plan of salvation is a wise plan indeed because he sent his own Son in the likeness of sinful flesh (Romans 8:3). It is wise because it works. God's salvific act is an act of perfection, coming from his substance ( 1 Corinthians 1:24, Hebrews 1:3).
The incarnation teaches the one gospel, that is, that the μονογενὴς Θεὸς took on human flesh and spirit in order to live human life under the law and to destroy the works of the devil by his death on the cross and resurrection( John 1:1,14,18, 1 Corinthians 15:3, 1 John 3:8).
Acts 20:28 said that God purchased the church with his own blood.
Even the sub-apostolic and pre-nicene fathers concur:
I have become acquainted with your name, much-beloved in God, which you have acquired by the habit of righteousness, according to the faith and love in Jesus Christ our Saviour. Being the followers of God, and stirring up yourselves by the blood of God, you have perfectly accomplished the work which was beseeming to you. (Epistle of Ignatius to the Ephesians, Chapter 1. Praise of the Ephesians Chapter 1).
So far as I know, "we are not our own, but bought with a price;" and what kind of price? The blood of God. (Tertullian, To His Wife Book 2 Chapter 3)
