Even most Christians will not go to heaven. We have to try and strive everyday. I feel bad to say this sometimes, considering how hard I try and fail all the time.
Culturally Christian is very likely to be spiritually dead. Passively believing in Jesus, not keeping His sayings, not trusting in Him, making no practice of Holiness, nor cutting things out of your life that displease God. We have to be on guard against the god of self. "I'm going to do what I want, when I want, where I want, how I want.", "I'm a good person". "It's not like I'm a murderer!"
We have to surrender to God, give up control, trust Jesus, do as He says, and even though we fail, we strive against sin. We are not good people, we are sinners, that need grace. If you think you are good, why do you need a savior? So you didn't murder someone, but God said if you hate your neighbor you are a murderer at heart.
We need Jesus every hour.
I would ask you then how can you tell the goat from the sheep at a glance. You know them by their works, an beyond that; most of us have not spent more than a trivial amount of time with Jewish people.
I think Satan wants to destroy them bitterly. I am not a fan of replacement theory, I think it's clear that promises are not revoked, and that there is a remnant, based on Romans 11, and I suspect Isaiah 65.
We are grafted in, and warned directly by the Apostle Paul not to attack them.
I went down that road. Replacement theology leads to hating your neighbor. I understand that there are those that try to use that to hide evil activities, but I choose to bless and pray for them anyway.
God will handle the rest of it. God is able to raise up anyone for any purpose. He has bowls made for honor and for dishonor.
I recommend just praying for them, it didn't do me any good back when I was into that stuff.
God knows the sheep from the goats, and I don't want to be found a goat.
Greatest Commandment: Love the Lord your God will all your heart, with all you soul, with all your mind, with all your strength, and the second command is like it: Love your neighbor as thyself.
On this hang the law and the profits.
