Surely that is true, that all evil will be cast into hell. Even sometimes nations fall because they become so evil, sometimes they don't fall and continue in evil.
But that does not speak to all God's blessings on this earth.
Mat 5:44 but I--I say to you, Love your enemies, bless those cursing you, do good to those hating you, and pray for those accusing you falsely, and persecuting you,
Mat 5:45 that ye may be sons of your Father in the heavens, because His sun He doth cause to rise on evil and good, and He doth send rain on righteous and unrighteous.
They just don't know that their rain came from Him. Some of them are like the philosophers at Mars Hill, with the memorial to the Unknown God.
Do you believe that Holy Ghost of Jesus sent to teach/lead/guide is teaching all these different doctrines to different people and denominations???
Many people do, and that's what leads to this idea that if you show a little respect for God, doesn't matter what doctrine you believe, anybody/everybody will go to heaven.
But God created man to have "Fellowship with Him", obviously that means a "Relationship" and "Communication" between God and man.
Israel closed their eyes/ears to Jesus, claiming to worship the same God they had worshiped for something like two thousand years, which Jesus really was the same God in the "Flesh", we know how that worked out for them.
So even trying to worship the true God in Heaven is "worthless" unless there is a "Relationship/Communication" in the only way God will accept, that is through/by the Holy "Ghost", of Jesus.
Beliefs, Church Rituals, Denominations, doesn't matter, the only thing that does is having this "Relationship/Communication" with God,
and as Jesus said, "You will know the truth", because the Ghost doesn't teach false doctrines or lies.
But just like Israel, they'll always be some still preaching their false doctrine as they pass through the gates of hell.
