Yes= Gospel= the good news.
“Every knee will bow and every tongue will confess that Jesus Christ is Lord.”
God did not start this thing in Eden to end up losing 95% of humanity.
GOD WINS!
We are all in the spiritual eden now, and there are people who have faith, and people who do not have faith.
To be saved to the Kingdom of God one must have faith in this life. In the apostolic record people died without having faith went to the prison part of Sheol, or had faith went to the paradise part of Sheol.
I believe now today that all people go before God and are judged, those with faith go into the kingdom, and those without faith go outside of the kingdom however the gates surrounding the spiritual city never close.
