None of us should ever pretend to understand God, because the simple truth is nobody understands Him. He ways are infinitely higher than our fallen, sinful and wicked ways. Our minds are corrupt, so it's impossible to understands God's ways with a corrupt and wicked mind.
So we are wasting our time pretending to know why He does what He does, the scriptures are too deep and too hard to understand. Our pastor said, we can study scripture all day every day for the rest of our lives and they will still remain mysterious. He said to watch out for those who claim to have figured them out, as they are deceived. We will all go to the grave and scripture will remain mysterious.
This is why we just take the scriptures literally, that's as close as we can get to understanding the mystery of scripture. As soon as we start adding or taking away, we go off into uncharted waters and we quickly become lost in our own foolishness.
Our pastor told us that we don't need to understand the Bible to be saved, all we need to do is believe in Christ and we are 100% guaranteed to be saved. So the whole argument of do we choose God or does He choose us is irrelevant to a believer.
