1) Did you receive any of this knowledge directly from God?
Well "knowledge" is a tricky word. we can know something intellectually, but mere head knowledge is not what Christianity is, or even what it is based on. God looks on the
heart, and sometimes I think this nebulous term is used merely to let us know it is not just our thoughts He is concerned with. Yet when we look into what the term refers to, we see it does indeed involve our thoughts. This is a Spiritual matter, Spiritually discerned. (Clear as mud, I know
Leaving aside the common modern usage of "know," there is the Biblical usage of it, as in Adam "knew" his wife. Hands on, experiential knowledge is what matters! Not mere intellectual assent, or being hearers only, but being
doers of the Word.
So when we speak of "receiving knowledge," it combines elements of all the above: input from human sources including Biblical scribes, Divine revelation to make sense out of it, and our own effort to walk in that light.
2) Is there a way to put it into words and explain it to me?
My best efforts will be to either quote Scripture, or paraphrase it. either way it's relevant to point you to the right place, so you can read the context for yourself. It is best shared by 2 or more people having the same type of hands-on experience with it, but this is also contagious among humans so watch out!
God gives us a taste of the powers of the world to come. This takes on seemingly infinite variety, and it is a growth process, not a battering ram knocking down your front door. Thankfulness may be our single greatest contribution to the process. (?)
3) If you can't, how can I receive this subject matter from God so I can understand it myself?
2 necessary steps are doing what you know is right, and prayer. Literally asking God to make these things real to you! It is possible to control our own desires, to try to shape them in a specific direction. I don't think we have
total control over that, but we can exert, and He seems to honor that.
4) If God is unable to provide me with insight and you are unable to put it into words, do I have any reason to believe it?
Well I also question everything, but I do so looking for solutions, and answers. I have put a lot into words, and I would say God is so much more capable of providing you with insight that even i can't stop Him!
