There are two places all of humanity can make reservations in Revelation, you will either have dinner with the Lamb or you will be dinner for the birds.
The truth is God is not willing any should perish and all have been invited to the banquet and as Jesus said in Matthew 22:14 “many are called, but few are chosen.” In that same parable Jesus explains why they were not allowed into the wedding even though they were invited as they “did not have on a wedding garment”, they were not clothed in the righteousness of Christ but came instead in the filthy rags of their own good works.
Paul wrote of this in Philip. 3:9 saying that he wanted to “be found in Him, not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith”.
