The true way given by God on Mt. Sinai for Gentiles to merit their place in the World To Come, is by being a Righteous Gentile. This means following the 7 Noahide Laws, living your life with these guidelines which will provide you with the ability to bring compassion, kindness, and love into your life and the lives of those around you.
There has never existed in Judaism a Messiah who is to serve as a virgin human blood sacrifice for sin. The Christian Church adopted this from ancient pagan societies, not from Judaism.
There has never existed in Judaism the idea of a Messiah who was born because God came swooping down and impregnated a virgin. Everything you've been taught about this coming from Judaism or from the Torah (old testament) is completely wrong. These are deliberate mistranslations of the word "almah" there which means young woman, not virgin. All women who gave birth back then were young women, except Sarah. If it had meant "virgin" it would have said "betulah" which actually means virgin and is used several times in the Torah when talking about actual virgins.
Also, God is not a man, and God says so several times in the Torah. If you believe God became a man, and you worship this man/God on top of it, you are committing idolatry. There has never existed the concept in Judaism that God becomes a man, is sacrificed for sin, and then descends to hell, rises back up after 3 days, and then goes to sit beside himself in heaven. ALL of this comes from ancient pagan religions, not Judaism.
So if you do want to continue to believe these things, fine, but realise the source of them is all. As a non-Jew, you were given long ago on Mt. Sinai your merit to have a place in the World To Come, and that is by being a Righteous Gentile. You do this by the 7 Noahide Laws.

Please also understand that Judaism does not now, and never has had the concept of Original Sin. We think this is an absolutely disgusting concept, and it is a twisted invention of the Church fathers used to control their followers. Judaism believes that everyone is born with clean, pure souls and it is our responsibility after we are born and attain the age of understanding, to either CHOOSE to blemish our souls or CHOOSE not to. It's called Free Will, and personal responsibility.
We also do not have anything or anyone that we have to go through to get to God. This is idolatry. It is a horrible thing the Church teaches that God is separate from us, that we are so filthy and worthless that God cannot stand to be near us. This is so wrong.
God breathed into us clean, pure souls when each of us were born, directly from His own "lungs", that is to say, His very ESSENCE. We have God with us always, our souls ARE a part of God, therefore we are never separated from God, not ever. You are not now, nor were you ever separate from God.
Were you aware that in Hosea, after the Temple was destroyed, the Jews asked God "What do we do now to obtain forgiveness as we have no place to bring sacrifices any longer?" God answered them "From now on, the prayers of your lips will serve as the bulls of sacrifice."
Prayer. That is all you need to obtain forgiveness. This was LONG before the Church adopted the pagan Jesus human sacrifice concepts and the idea that we are born so filthy that we cannot even approach God TO pray in the first place because He won't hear us due to our supposed "sin".
This is an abusive, horrible teaching, and it needs to stop.
The animal sacrifices were done for ALL of the 70 nations, every year on Succoth. Not just for the Jews.
Furthermore, the animal sacrifices were NEVER meant to be a permanent thing. Permission was given for them because it was the way of the people who became the Jews - Abraham was the first Jew, according to Judaism, and it was out from this type of paganism that he and his followers came. His own father was an idol maker, and his society was steeped in animal sacrifice, even human sacrifice.
It is very difficult to wean people off one thing right off the bat and change them to something else. This is why the animal sacrifices were allowed to continue, but they were NOT meant to be permanent. Prayer and direct communication with God (without any intermediary) was the actual goal. And this is what we have now.
