EVERYONE is aware of God's nature
“Even the Spirit of truth: whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth in you, and shall be in you”
“love is of God; and every one that loveth is born of God, and knoweth God. He that loveth not knoweth not God; for God is love.”
"Blessed are the pure in heart, for they shall see God."
the commandments of goodness are felt in everybody all over the world... that's why in all the major religions and philosophies repeat the same standards of goodness... certain truth's are universal but salvation isn't.
“joy shall be in heaven over one sinner that repenteth, more than over ninety nine just persons, which need no repentance.”
“Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.”
