to me this particular issue isn’t relevant.
If Christ was given authority by God to forgiven sins and pronounce judgement, does it really matter if he is God or not? either way our actions needed to be saved are exactly the same.
Well, yes, because it fulfills Scripture. And it’s about more than simply the authority to forgive sin and pronounce judgment.
The deity of Christ is the cornerstone on which redemption rests. No one else could have died and paid for our sins, regardless of whether our actions are the same.
John 1:1-4 In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made. In him was life, and the life was the light of men.
John 1:14 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
John 8:58 Jesus said to them, Truly, truly, I say to you, before Abraham was, I am.
John 10:30 I and the Father are one.
John 14:8-13 Philip said to him, Lord, show us the Father, and it is enough for us. Jesus said to him, Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, Show us the Father? Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works. Believe me that I am in the Father and the Father is in me, or else believe on account of the works themselves.
Matthew 1:22-23 All this took place to fulfill what the Lord had spoken by the prophet: Behold, the virgin shall conceive and bear a son, and they shall call his name Immanuel (which means, God with us).
Colossians 2:9-10 For in him the whole fullness of deity dwells bodily, and you have been filled in him, who is the head of all rule and authority.
1 John 2:22-25 Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. No one who denies the Son has the Father. Whoever confesses the Son has the Father also. Let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father. And this is the promise that he made to useternal life.

If you don't know Him, you have a problem. There are no actions involved it's is belief.
John 17: 3 And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
