In a lot of cases the issue is something that I have struggled through. In that case there will be one or several passages of Scripture that I have identified that help resolve the issue. That being the case, I will suggest that we look at those passages together and talk about what they say.
If it is the case that it is a topic that I have not considered, then “I don’t know, but I will find out and get back to you.” Is my go to answer. I then go struggle through the issue which allows me to do what I said in the previous paragraph.
Bottom line, it does not matter what I know or what I think. What matters is what God, in the Bible, says. That is what I want to be the foundation of my kid’s faith. The foundation of those others whom the Lord may give me the opportunity to encourage.
