Good point, Popery isn't a guarantee of anything
The one who says, “I have come to know him,” and yet doesn’t keep his commands, is a liar, and the truth is not in him. 1 John 1:6
“Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’ Matthew 7:21-23
