The need for Certainty in anything else but Christ is a defect of the natural (carnal) mind.
The Holy Spirit teaches us and guides us in all things. All things! Our reason, past experience, and studies are nothing, and usually a hindrance, to truth. We are not to lean on our own understanding in anything, no matter how plain and simple it may seem.
The Bible doesn't mean that we are suppopsed to ask God what we are to have for breakfast or what color shirt to wear today. You taking that further than what was intended in Scripture.
The Holy Spirit has knowledges of all things, past, pressent, and to come. It does not need sources and sites, yet the natural-mind does demand it. This does not mean we do not research or ignore reports or automatically doubt scientific theory or methodology: we listen to all that is presented and surrender to guidance.
God created the natural mind and its processes. There is nothing wrong with that. I doubt quite a bit of stuff that other people's natural minds create and try to foist on me.
Many bizarre things are attributed to the direction and sanction of the Holy Spirit, the Crusades are a fine example, as is the Spanish Inquisition and the Salem Witch Trials. Or the church that burns the Koran. Or those that see Obama as the antichrist. Or those that protest military funerals. What elements must be present for such discernment to be seen as reliable?
Really... who is attributing those things to the Holy Spirit??? Seems you are assigning values to others without warrant or justification.
Only one, really: love. Scripture defines this love and the Father exemplifies this love, as this is His nature. Christ is the incarnate description of this love. Matters of fact and matters of truth are wholly different. Love alone sees the reality of truth and love alone dictates how we are to live in the world. Those questions of worldly facts can be quibbled forever. We can go from source to source to source and find what we want or confusion. Which then begs the question, how important are they?
You really have a problem with people who think for themselves and expect facts to be supported and verified before simply accepting liberal dogma don't you??? It would be so much easier if you could post your ideas without these pesky people expecting you to back up your ideas with factual, corroborating data, right?
