We’re commanded to avoid foolish questions (Tit 3:9); so, not all questions are good. To understand the difference between foolish questions and wise questions (Ep 5:16), we ask: What kinds of questions are foolish? This particular question isn’t foolish; it’s wisdom.
The context is profitability (Tit 3:9b), implying a way to measure and evaluate questions. Is the question profitable? depends on what we value. To ask meaningful questions we must have a proper motive and direction to orient our asking.
Is the atheist seeking to destroy another’s faith or value system? Or distracting from the soul-wound they’ve been using to justify their hatred and dismissal of God? Or searching out an explanation to resolve what seems insurmountable inconsistency, extreme lack of credibility hiding behind the façade of religion?
Is the church-goer showing off, looking for respect, to be valued for their knowledge of scripture? Are they looking to generate controversy and cause divisions and offenses? (Ro 16:17) Or looking to avoid responsibility by casting doubt on instructions and raising up controversy? Or trying to learn and understand, so they can rightly order their thoughts and actions?
Is the biblical scholar ever asking, ever learning, yet never able to come to the knowledge of the truth? (2Ti 3:7) Are we content with theological exercises and pontifications, ducking relational responsibility, ignoring sins of the heart? Are we content piling up knowledge, without regard to the poor (Ga 2:10), the fatherless, orphan and widow?
Or are we asking so we can deliver ourselves from the bondage of our lies (2Ti 2:25-26), freeing ourselves to serve more effectively, more joyfully and fruitfully, equipping ourselves unto love and good works? (Tit 3:14)
If we’re after God and His kingdom (Mt 6:33), if we fear God and want to please Him (Pr 1:7), our questions should bring us closer to God, into more alignment with Him, more obedience to Him, more love for Him.
Jesus asked a lot of questions; we can learn from watching Him. He was always pointing others to the kingdom of God. His questions penetrated hearts and exposed motives, helping us see our need for Him and pointing us toward a more perfect knowledge of His Way.
