Is a good question to ask Jesus. It is quite possibly the question to ask Jesus. Your tone and intention, however, matter a great deal. There is a healthy way and an unhealthy way to ask such a question. Whichever you choose will determine your ability to clearly hear his answer, and maybe even determine the kind of answer he gives you.
Do you ask with skepticism or receptivity?
With arrogance or humility?
With incredulity or trust?
With certainty in your own answer, or acceptance of his?
With interest in your own agenda, or a yielding to his?
With a hard heart, or a soft heart?
With an already-made-up mind, or a teachable mind?
With a closed soul, or an open soul?
