I tell you this, brothers: flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. 1 Cor. 15:50, ESV
There are only two religions in the entire world. There is genuine Orthodox Christianity and then every other form of religiosity including humanism. The latter are all opposed to the truth and are part of the rebellion against the sovereignty of God. Genuine Orthodox Christianity is made up of those who have been redeemed from the slave market of iniquity. This slave market preys on people and keeps them in bondage to the flesh. On the other hand, Genuine Orthodox Christianity, which is the Church, is spiritual. Those in it are adopted into the family of God. Those spiritually alive right now await the completion of their redemption. Those who have already died are with the Lord now. Those who remain are in process. This process is their progressive sanctification, which is the mortification of the deeds of their flesh, which is sin. However, all outside of the Church are in their sins and can only operate in the flesh.
