Pinging you to #608.
Deuteronomy 23:2 - "No one born of a forbidden marriage[a] nor any of their descendants may enter the assembly of the LORD, not even in the tenth generation."
The key phrase there is ‘assembly of the Lord’ ~ does not equate to heaven in my study Bible rather worship services or an exulted office/position back in Moses day.
You can simply pray the prayer of salvation (see Romans 10:8-10) or you can continue to act as experts trying to trip up true believers but you can’t have it both ways. Choose ye this day who you will serve.
