Mating and dating
When it’s time to reproduce, they sword fight each other with their male organs – each attempting to inseminate the other.
It’s a rough experience; the flatworms literally give each other stab wounds.
To say or believe that another person is “everything” or the most important thing in one’s life is idolatry, which is sin (Galatians ; Colossians 3:5).
Also, we are not to defile our bodies by having premarital sex (1 Corinthians 6:9, 13; 2 Timothy ).
Imagine if you could only mate during the full moon, or if you had to worry about your partner eating you.
Maybe you’d choose to reproduce without a partner, or fight about who gets to be the male.
When one is in a committed relationship, whether dating or courting, it is important to remember to love the Lord above all else (Matthew ).
Sexual immorality is a sin not only against God but against our own bodies (1 Corinthians ).
