What we think is good for our kids is good for us too. Of course many parents now days don't even caution their children about what they see, where they go or what they listen to. As Christians, we have the Holy Spirit living inside of us. Think about what that means, He sees what we see, He hears what we hear, He goes where we go. If you are going to evil places you are taking the Holy Spirit with you.
People are very good at justifying the things that they do.
No, there is nothing wrong with dancing, David danced in the presence of the Lord, but think about where you are. If your answer is no then you have no business being there either. And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. Another point that I think is too often overlooked is this.
