Have you never sinned on becoming a Christian,
Someone who claims to not sin after becoming a Christian is a liar and doesn't read his Bible.
if you have, then who is the person who redeems you according to 1 John 2:1? Please state your answer.
Christians are not redeemed according to 1 John 2:1.
Again, taking things out of context will cause you nothing but confusion when reading the Bible.
If your answer is Jesus then how does he offer a sacrifice for that sin if he is not high priest, since high priests were the only ones who could offer sacrifice for sins on behalf the people of Israel?
Once again, your paradigm of beliefs has clouded your thinking.
What sacrifice would Jesus give that would redeem the whole world if He were merely a man?
There is nothing, as King David wrote:
None of them can by any means redeem his brother, Nor give to God a ransom for him—For the redemption of their souls is costly, And it shall cease forever—That he should continue to live eternally, And not see the Pit. . . . But God will redeem my soul from the power of the grave, For He shall receive me. Selah - Psalm 49:7-9,15

The only sacrifice that could pay the price of sin (which has eternal consequences) is someone who has eternal value, a man's death satisfies the needs of justice, but his death cannot redeem another man from his sin. So, even if Christ (if He were only a man) were to live a perfect life and then die, His life ould only valuable enough to redeem His own life, and no one else's.
BUT
Since Jesus is NOT just a man, which would make the entire cross pointless, but God Himself in the flesh, God sacrificing Himself to pay for the sin of man is MORE than enough to redeem ALL OF MANKIND, because God has the most value, and His value is eternal, because He has existed from of old, from everlasting to everlasting, His years never end.
He is the most valuable thing in all of existence. Only HE HIMSELF could pay the price for sin. That's why HE HIMSELF came willingly to die for us.
See, your problem is that you think that the whole Bible applies to and is written just for you.
Thing is... It's not!
If you think that it is, you need to get the bigger picture. Change your paradigm of thinking, because as it stands now, you're walking on thin ice above the flames coming out of the pit of Hell, which is a real place, and it will burn for eternity with you in it, unless you repent towards God and ask Him to save you from your sins, because there is NOTHING you can do to save yourself.
Your answer is this:
Jesus Himself, being God, the Word, in the flesh, offered HIMSELF as a sacrifice, the spotless Lamb of God.
If you can't offer a decent response to this there is no point in replying.
You're bringing up a totally different issue (sharing and non-sharing of glory) which I will address if you want me to, all you need to do is answer the question which you did not do, I'm curious what you answer will be. The questions again:
Does Isaiah 64:8 say that Jehovah is the Father, yes or no?
No.
It says the the LORD is OUR [the Nation of Israel's] Father.
When every knee on heaven and earth bends to Jesus (Phil 2:8-11), to whose glory is it to, his own or the Father?
Yes.
