Let's consider what the Bible teaches.
We know that Jesus was a man, but the Bible tells us that God is not a man.
God is not a man, that he should lie; neither the son of man, that he
should repent: hath he said, and shall he not do it? or hath he
spoken, and shall he not make it good? (Numbers 23:19, KJV)
And also the Strength of Israel will not lie nor repent: for he is not
a man, that he should repent. (1 Samuel 15:29, KJV)
Jesus calls himself "the son of man" in many places.
When Jesus came into the coasts of Caesarea Philippi, he asked his
disciples, saying, Whom do men say that I the Son of man am? (Matthew
16:13, KJV)
But God says He is not "the son of man."
Therefore, Jesus cannot have been God.
But who was he, then?
Jesus was a human, just like ourselves, but who was born into our world as God's Son--a son who already existed. He had not previously existed in human form, but entered human flesh upon his birth in Bethlehem, when he came into the world.
Wherefore when he cometh into the world, he saith, Sacrifice and
offering thou wouldest not, but a body hast thou prepared me: (Hebrews
10:5, KJV)
If Jesus had been God, Jesus could not have died, for God is immortal.
Now unto the King eternal, immortal, invisible, the only wise God, be
honour and glory for ever and ever. Amen. (1 Timothy 1:17, KJV)
Who only hath immortality, dwelling in the light which no man can
approach unto; whom no man hath seen, nor can see: to whom be honour
and power everlasting. Amen. (1 Timothy 6:16, KJV)
And this makes sense, because a God who could die would not really be God at all.
While Jesus is not God, God has given us permission to worship him.
5For unto which of the angels said he at any time, Thou art
my Son, this day have I begotten thee? And again, I will be to him a
Father, and he shall be to me a Son?
6And again, when he bringeth in the firstbegotten into the world, he
saith, And let all the angels of God worship him. (Hebrews 1:5-6, KJV)
Even this text that gives us permission to worship Jesus helps us to understand that Jesus is not God, because if he had been God, no permission to worship him would be needed. Furthermore, the angels of heaven, who already worship God, would not need to be told this.
But God was in Jesus Christ.
To wit, that God was in Christ, reconciling the world unto himself,
not imputing their trespasses unto them; and hath committed unto us
the word of reconciliation. (2 Corinthians 5:19, KJV)
And Jesus taught this himself.
Believest thou not that I am in the Father, and the Father in me? the
words that I speak unto you I speak not of myself: but the Father that
dwelleth in me, he doeth the works. (John 14:10, KJV)
The God who dwelt in Christ has, of course, always existed. God was never created. But Jesus' human body was "prepared" for him, i.e. created, according to the Bible. So within the person of Jesus we find both the created and the Uncreated, both the finite and the Infinite.
If Jesus had been God, he could not have been tempted.
Let no man say when he is tempted, I am tempted of God: for God cannot
be tempted with evil, neither tempteth he any man: (James 1:13, KJV)
But Jesus was tempted.
Then was Jesus led up of the spirit into the wilderness to be tempted
of the devil. (Matthew 4:1, KJV)
It was not God who was tempted in the wilderness. Jesus, as a man, endured temptation on our behalf--and was victorious. This was our example. We do not need to sin; we can quote scripture, as Jesus did, and maintain our loyalty to God.
Everything Jesus did was to be our example. And he taught us who God was.
Jesus saith unto her, Touch me not; for I am not yet ascended to my
Father: but go to my brethren, and say unto them, I ascend unto my
Father, and your Father; and to my God, and your God. (John 20:17,
KJV)
Jesus' father was his God.
Ye have heard how I said unto you, I go away, and come again unto you.
If ye loved me, ye would rejoice, because I said, I go unto the
Father: for my Father is greater than I. (John 14:28, KJV)
Undoubtedly, your questions are well-founded, based on the confusing errors that abound. The Bible, however, is unconfusingly clear, and we can trust it.
