Between........................................
MARRIED COUPLES.
Hahahaha "sharing it!" Hahahahaha - that has taken on another meaning. You're talking about....."swinging?" Hahahahaha
"SHARING IT...." Is that how swingers justify it? Haha
I don't know what kind of Bible you're reading Lursa.....or, if you've even read one. Your arguments are so out of touch with it.
This has nothing to do with breaking God's Word on compassion, forgiveness, peace and brotherly love (although in the case of adultery - it does.
It hurts the cuckolded partner. It hurts and may even break a family).
Just so you know.......here are some verses about fornication.
2 Cor 12:21
I am afraid that when I come again my God will humble me before you, and I will be grieved over many who have sinned earlier and
have not repented of the impurity, sexual sin and debauchery in which they have indulged.
Ephesians 5
3 But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people.
Gal 5
19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery;
Hebrews 13
4 Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral.
1 Cor 6
9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men
1 Cor 6
18 Flee from sexual immorality. All other sins a person commits are outside the body, but whoever sins sexually, sins against their own body.
1 Thessalonians
3 It is God’s will that you should be sanctified: that you should avoid sexual immorality;
4 that each of you should learn to control your own body in a way that is holy and honorable,
5 not in passionate lust like the pagans, who do not know God;
