Question posed:
"Well Todd, this person is a fornicator, goes to the casino almost every weekend, smokes weed, and curses a lot, and this is just what I know about him, there may be more. Would you want this person in your life? Todd, I appreciate your response, but it really didn't answer my question, should a brother or sister question what God has spoken to us?"
The question itself is framed in a way that "poisons the well"...its conclusion is assumed by the negative character represented.
Aside from that.
A few things:
1. You should share what God has spoken to you with others whom you trust ( those who have shown good discerning in the past)Believers only, unbelievers cannot understand or discern spiritual things so their answer is highly speculative.
2. You should share it with spiritual leaders if you have those kind of men who are capable of discerning the voice of God.
3. You should share it with your wife if she is capable of discerning and hearing the voice of God herself.
Those whom I personally would NOT share what I believe to be God.
1. Cookie cutter Christians who do not actually discern, but in fact simply measure all things against a doctrinal grid, or some church's position on the matter.
(case in point, I don't ask cessationists to help discern or bring light upon a prophetic word, word of knowledge etc) because from the outset they have nothing to offer except a doctrinal position).
2. Hyper-spirituals who are as equally undiscerning as a cessationist because they pretty much accept anything that has a 'spiritual flavor' to it.
3. Christians who do not care about your spiritual condition or welfare.
Caveat #1 if you hear something along the lines of "Hey, divorce that mean wife and get this much prettier model" The cessationist if biblical will quickly see this is not aligning with scripture (cessationist or not) and get it right when he tells you, your listening to something devilish.
all that to say...if you follow God relationally, and listen for his voice as you would his child, you must seek the godly counsel of those who also follow God relationally and listen for the voice of the Spirit.
