McNap, The GOD of the Scriptures who Created all things made the Rules/laws to be followed by HIS Creatures and is NOT "double-minded".
The Creator said the Male and the Female(married) were to be "one flesh", Just as the Female was created from the "flesh" of man.
GOD called man's sexual relationship between other than one's wife(female)--SIN.
Rom.13: isn't speaking of erotic/love, but brotherly--Philo/love.
Well, according to Matthew Jesus said:
But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery. (Mat. 5:32)
This means you can either commit adultary with anyone who is married/divorced or you have to be married/divorced yourself.
If I am single and have never been married and I have seks with a single girl who has never been married... how can it be a sin?
A sin is a violation of one of the 10 commandments.
I can even have seks (or marry) with a divorced girl as long as her ex-husband put her away for the cause of fornication. I guarantee you, it's no sin if I have seks with such a divorced girl. If she loved her ex-husband well enough, she wouldn't do any sexual immorality. One does sexual immorality because there is someone outside the marriage whom you love more. Jesus means you should marry the one you love the most. Therefore he makes exceptions. Why would you stay married to your wife anyway if you know she has more love for someone else?
I agree with the topic starter.
She said she believes premarital seks is no sin.
As for the brotherly-love-thing you mentioned... if practising homosexuals have charity for every brother and even for irreligious people they are not sinning?
I mean, I spread the gospel on the streets and sometimes people ask me questions regarding their gay-friends.
Or suppose some gay brothers remain celibate thanks to brothers like you and they fall in love with one another in our church because we have allowed them there for their celibacy, then what should we do according to you?
Because I'm not going to hinder anyone else his love.
Or what if I tell the gospel to an atheistic gay boy that already has a relationship with another gay boy and he wants to accept Jesus in his heart...
You think I will force him to return to singleness? Or that I make him feel guilty?
Jesus said: All those who the Father gives me will come to me. Him who comes to me I will in no way throw out. (John 6:37)
