I am certainly with you on this. There a lot discussions or arguments going on about things which are at best fuzzy to me. I admit that over the years some previously fuzzy things have been made clearer, but that is far from being the whole loaf. I continue to read the entire Bible regularly in addition to any specific studies I may get into.. But, a number of things I put up on a shelf because I don't understand them and at this point they do not fit into the vision I have. I am careful to talk to God [pray] also regularly so as not to give up on anything important and to ask Him to clarify for me anything that I need when I need it. He always knows. I do not.That was my feeling too, but the one most theologically rejected.
My feeling is that God will provide all the important answers when we ask Him a question.
Some verses are very difficult to understand.
Who are the sons of God and the daughters of men?
Who really cares?
In the end, what difference does it make?
Jesus made sure that we understand what we NEED to know.
So, I agree that we know all we need to know and do not need anything else.
The O.T. was written 4,000 years ago!
Who can know what some things mean??
Some of the discussions on this forum [and others], I have not entered into for the above reasons. If something catches my attention, I may read some of the posts, but I don't want to waste time on something that would not seem to be edifying for me or for someone else.
What does God want from us? I am purposely not trying to answer that question now.
