What do you think of "born-again virgins"? If someone has pre-marital sex with more partners than they can remember, can they still just stop having sex and claim to be a born again virgin? They always say "you can't turn a ho into a housewife" or "why buy the cow when you can get the milk for free" so should people who are not pure anymore even try to be born again virgins? What is the point in trying to make yourself pure for your future husband/wife if you are far from pure and never will be pure again?
Uhmm... the correct term would be a reformed woman. I think it's wrong to judge someone because of their past. Everyone commits a mistake and no one is an exemption. I'm not saying that doing premarital sex is okay because it is definitely not!
The bible cleary says in Ephesians 5:4-5
"But sexual immorality and all impurity or covetousness must not even be named among you, as is proper among saints. 4 Let there be no filthiness nor foolish talk nor crude joking, which are out of place, but instead let there be thanksgiving. 5 For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous ( that is, an idolater), has no inheritance in the kingdom of Christ and God."
1 Corinthians 6:12-20
12 “All things are lawful for me,” but not all things are helpful. “All things are lawful for me,” but I will not be dominated by anything. 13 “Food is meant for the stomach and the stomach for food”—and God will destroy both one and the other. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. 14 And God raised the Lord and will also raise us up by his power. 15 Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a prostitute? Never! 16 Or do you not know that he who is joined[d] to a prostitute becomes one body with her? For, as it is written, “The two will become one flesh.” 17 But he who is joined to the Lord becomes one spirit with him. 18 Flee from sexual immorality. Every other sin[e] a person commits is outside the body, but the sexually immoral person sins against his own body. 19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, 20 for you were bought with a price. So glorify God in your body.
Now that you have accepted Jesus Christ as your personal savior. You ought to abstain or flee away from things that are not desirable and glorifying God.
2 Corinthians 5:17
Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!
