Acceptance = Understanding?

If there is a theologian or enlightened one among you out there, please show me where I have misunderstood or failed to understand this.
I have, in the past 2-3 years, come across various speakers (read: preachers and pastors) whose messages I have struggled to make sense. Some of these involve “prophecies” and I have made an entry on this before, in particular in relation to Nalliah and his misguided “prophecies” about the recent Australian federal elections. Others involve healing and “giftings” which frankly, sound just like some medicine sellers to me.
My problem is this. Whenever I tell someone about my difficulties with understanding (let alone accepting) these teachings, one of the responses I get is “don’t worry, I used to be like that too”. Is time the impediment to a clear understanding? Does understanding come with the passage of time alone? Are those who do not agree with such teachings “behind the 8th ball” somewhat?
Ok – maybe it’s pride but that’s not the point. The point is to provide an explanation, not a sagely and condescending “you will understand in time” response. If one truly understands, surely one can explain? I think the next time I get this response I will hold this person down and insist on an explanation and suggest that no matter how much time passes, he/she doesn’t understand either. That person has merely stopped questioning and accepted everything. That is not understanding. That is quitting. That person has simply thrown up his or her hands and say I give up, I’ll just accept anything. Is this understanding?
