(Proverbs 18:17 KJV) He that is first in his own cause seemeth just; but his neighbour cometh and searcheth him.
It is not only acceptable to ask questions, it is important. It may even be a requirement. There may be times when we must accept the first word. There are times of crisis and short encounters but often we have time to “searcheth” (examine NASB) (2713) what people tell us. It isn’t even that people are trying to deceive. Sometimes it is just a case of being too lazy to examine what they remember.
We are given the responsibility to think and assist others in thinking. Questioning is important. Being considered a skeptic might be the difference between knowing the truth and living a lie. You never know. When you ask your child if they washed their hands it is usually just a precaution but there will be that time when it will make a difference between getting sick or staying healthy. The sickness can vary from a runny nose to a fatal disease.
So? Don’t be afraid to ask questions. The masses are often too happy with their bread and circuses. We are to be salt and salt makes a difference.
