Do not be deceived: neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men[a] 10 nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.The word practice is used in both Galatians 5:21 and 1 John 3:9 and practicing sin is descriptive of those who are not born of God. 1 Corinthians 6:9-11 contrasts the unrighteous who practice such sins in contrast with those who do not practice such sins and were washed, sanctified and justified. No contradictions, just scripture harmonizing with scripture. If the Roman Catholic church could not convince me that truly "saved" people can truly "lose their salvation" then neither will you be able to. Have a nice day.
Why would Paul tell believers not to be deceived concerning those things unless it was a warning?
Explained again Gal5:19-21 in relation to 1John3:9
Anyway, I have been on the internet long enough to know people rarely, if ever change their minds, so that was not my purpose.
You have a nice day too
