Did you know that if we don't live a holy life before God we are litteraly doomed? Does anyone care about holiness? [Spirituality & Religion]

Alot of preachers talk heresy these days, to get money and maybe fame. The story goes like this, God created people and then one of his angels fell. That fallen angel decided to fight against God by making people disobey God(fall of man) and sin. We were all doomed to end up in hell because of sin and God cannot dwell amongst sin. He is so holy. Jesus came to die for our sin so we could get a chance to be reconciled to a holy God. That cleared a huge part of the way in making it into heaven again. Now we had to repent of our sins and live holy lives before God inorder to make it into heaven cause without holiness no one will see God. He is so holy that his only son litteraly had to die so we could have a chance. Holiness is the key word here.
