What does the Bible say about premarital sex?

Question- What does the Bible say about premarital sex, and if a non-virgin repents, do they become a virgin according to God?

Answer- In the Bible, premarital sex is referred to as fornication, which is a sin distinct from adultery. Since adultery is defined as either cheating on your spouse or having relations with another person's spouse, it would make since that fornication would refer to two unmarried people having relations. Hebrews 13:4 says, "Marriage is honorable above all and the bed undefiled. But fornicators and adulterers, God will judge." Also, remember that when Joseph was betrothed to Mary, although they had not had sexual relations, Mary was still considered Joseph's wife because of the vow that they had made. (Matthew 1:18-19) As far as secondary virginity, there is nothing in the Bible that mentions whether God considers repentant non-virgins as actual virgins. However, one of the chief blessings of the new covenant is that when you place your faith in Christ, God says, "Your sins and your lawless deeds, I will remember no more." (Hebrews 8:12) But there is a truth that is even greater than this. The Bible says, "If any man be in Christ, he is a new creation. Old things have passed away. Behold all things have become new." (II Corinthians 5:17) When a person comes to Christ, not only does God see him or her as a brand new person, he or she actually becomes a brand new person. For this reason, I have no problem with the term "secondary virginity."
