It's OK to ask questions. In fact, if you ask the right questions it will change your life. Don't be afraid to ask questions of God, of the Bible, about work, family, etc. Learning the art of asking questions is more important than the answers that come. When you focus on asking questions (even of the answers that come) your percepts will change.
Recently I've begun asking questions about the authority and inerrancy of the Bible. There is a modern day view of the Bible that says..... I ask, where did this view of the Bible come from? Who started this view of the Bible? and many others. The actual questions are not as important as developing the freedom to question anything and everthing. Even though I say this, I also add a word of caution. Be careful not to get in the habit of asking question at the wrong time. Be careful not to ask question instead of fulfilling your responsibilities (as a child will often try to do). Question can often be used as an excuse to not do anything. When I say ask questions, I mainly mean to fulfill your responsibilities first, then at the proper time feel free to ask your questions.
Again, it is not any one question that is important. Usually when I ask questions I get more questions. If I only focus on trying to get answers, then I won't get more questions. When I'm on a quest, as I often am, questions will come in a string, one after another. When I ask the first question, sometimes I get an answer, but sometimes I just get the next question.
Often times we hold onto our misconceptions so tightly. One question won't set us free. It often takes a whole series (or multi-series) of questions before we begin to experience freedom. Part of walking into this freedom involves the crumbling of our tightly-held-onto belief system. The many questions allows our minds to look at and question our beliefs from many different angles. In reality, asking questions primarily has to do with tearing down our own inadequate belief system. This can be, and usually is, a very scarey process because questioning can demolish much of our core beliefs. This was very scarey for me when I first started questioning my own beliefs. It's like having almost everything that I relied upon, the things that I held to be true, all just crumbled to the ground. To be sure, at the beginning it took a period of some months before my incorrect beliefs began to crumble. At the time I didn't know what was happening. Yet, with the crumbling of my old beliefs came a new freedom, a freedom to search for that which was true.
Much of the time we have received our belief system from our parents or other authority figures in our lives. At the time we received our beliefs we were very young and didn't evaluate or question what we were thought.
It might be said that if you question the bible and your beliefs that your faith and your belief in the Bible may be destroyed. How true, as it should be, if your beliefs have been built upon errors and traditions of men.
However, truth can stand up to questioning. Upon deep and sincere questioning, truth will stand up and found to be truth. But errors, mistakes, and faulty belief systems can not stand up to thorough question.
One of the biggest benefits of questioning yourself and your deepest beliefs is that which is false will crumble. In the end, in the midst of all the rubble, you will find that which is true. Then you can build your beliefs upon truth. Truth can stand the test of time.
