There is nothing wrong with questions. There is nothing wrong with wanting to be sure of the truth. You need to not be afraid to ask questions. You need to verify things for yourself.
Where we get into trouble is when we stop at the question.
We are admonished to “Seek and You Will Find” and to “Knock and It Will be Answered”. When we have questions we need to do something about getting an answer.
Don’t stop at the question. Notice that in order to find the answer, you need to seek it out.
For your faith to work, you must be absolutely sure beyond a doubt.
Faith comes by hearing, and hearing by the Word of God.
There is no such thing as “blind faith”. Faith is based on knowledge — but not just any kind of knowledge, knowledge of God’s Word.
The next step is to believe and act on your faith. This is knowing that God’s Word is true no matter what your senses tell you about your circumstances. Let God be true and every man a liar.
What can hold you back? Doubt and unbelief. Any doubt in your heart can hinder or nullify your faith.
If you have questions, you need to do something to get them resolved one way or another. Let not any who is double-minded expect anything of God.
If you don’t have time and need an immediate miracle, then in the meantime get others to agree with you in prayer.
Do whatever you need to do to be certain. This process will be different for every person, but the first step for everyone is to open yourself up and ask the Holy Spirit to guide you into the truth — whatever that truth may be, even if it flies in the face of some of your favorite pet theories. The next step is to get into the Word and read in the bible what God has to say about the subject. Dwell on it, think about it, meditate on it. To supplement your personal study, find good bible-based books/tapes that teach on the subject.
It is not wrong to question as long as you do something about getting your questions answered and resolved.
