It is more than safe to say that absolutely NO “illegal aliens of Adam's fallen race” (i.e., unrighteous sinners) will enter into Almighty God’s Holy and Righteous (Perfect) Heaven (1 Cor. 6:9-10).
Read what also the Bible teaches about what will NOT be in God’s Holy Heaven.
You call Me the Way and walk Me not!
You call Me the Life and live Me not!
You call Me Master and obey Me not!
You call Me Bread and eat Me not!
You call Me Truth and believe Me not!
You call Me Lord and serve Me not!
If I condemn you blame Me not!!
We can NEVER illegally enter Almighty God's holy Heaven. It is only through God’s Son that we have forgiveness of sins and fellowship with God the Father.
