Leviticus 18:6
"None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD."
Decency seems to be a thing of the past. There used to be a day when men and women were dressed decently around each other. In those days you didn't have as many problems with the opposite gender as you do today. One of the reasons is because they dressed decently around each other.
In Leviticus 18, God makes a call for decency among His people. Several times in this chapter God uses the phrase, "...to uncover their nakedness..." God goes through several relationships where they should be decent in front of each other. One then may wonder what God defines as"nakedness." Isaiah 47:2-3 shows us that when the thigh is uncovered, then a person is showing off their "nakedness." In other words, God is teaching that even among family members there must be a decorum of decency with each other.
God understood the depravity of mankind. He understood the importance of family members being decent in front of each other. Because God wanted to keep His people pure from the sins of the world, He commanded them to dress decently, even in front of their own family members. God knew this would help family members from doing things to each other that would hurt and take away their innocency. Let me give you some thoughts on being decent with each other.
First, be decent with your conversations. I know this sounds strange, but what you say will eventually become how you live. Just because it is your immediate family doesn't give you a right to be off-color with your jokes and conversations. I believe it is good to avoid sexual conversations and innuendos, especially in front of your children. If you keep the conversations right, then you'll keep the clothing right.
Second, never let your children bathe together. I don't care how young they are, you should never let children, especially of the opposite gender, bathe together. There needs to be a respect of one's privacy. You will break down the walls of decency when you allow your children to bathe together.
Third, NEVER let your children of the opposite gender be alone in a room with the door shut. You may say, "I trust my children"; that is your first mistake. That is exactly how bad things happen in a home. Too many bad things can happen behind closed doors that parents will later regret.
Fourth, dress decently around the home. I believe it is good that you stay properly dressed in your home. Whatever dress standards you have in public should be the same dress standards in private. Breaking down the walls of decency is done when you think you can be indecent around your immediate family.
Fifth, never swim together indecently. I know there are many who will disagree with me on this subject, but why is it okay to be indecent in water when it's not right to be indecent out of the water? There are things we will do around a swimming pool that we would never allow in the home. Decency is right no matter where you are.
Last, teach your children the importance of coming to you when one of their siblings are indecent. It is important your children understand that they always have a right to tell you when indecency is happening. This will keep everyone on guard.
If we learn to be decent in the home, then we will certainly be decent outside the home. Yes, our society needs a revival of decency, and the revival will start in the home. Understand that decency will keep purity in tact.
