I’m surprised by so many negative changes that we are experiencing in the world for sometime now. Normally, you are not meant to get attracted to your father, mother, siblings or any other person you are related to but people have changed this narrative.
I have seen cases where people marry their siblings and even their cousins. It’s important to be aware of what God wants and what God doesn’t support. God is not in any form or littlest form of support when it comes to marrying a relative.
Leviticus 18:6 tells us that; “None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD.”
Even if you ever see the nakedness of your relative, it should never move you an inch because there should be absolutely nothing that should look attractive to you.

There is a reason for everything and it is important to learn the general basics of life. In no circumstance whatsoever should one get sexually related to his ir her family member.
I know that this is done in some countries. I have heard about so many countries where cases like this happen and they are not even seen as a big deal. But even though the government is not saying anything about it, a big deal will continue to be a big deal.
If you have any family member or relative making advances at you, pray about it and teach them what the Bible says. That will help them to change.
