For me, I believe Scripture when it tells of God's wrath, and all should be literally afraid of it if they are not one of His own. There is nothing else to do with those verses but believ them...and many there are of them to read. That the Scripture denotes anthromorphological attributes to God (as in He is a "jealous" God etc) makes it very easy to understand (for me.) Sometimes we forget that we are made in God's image, not He ours. So if we can become angry, surely God can also! He threw Lucifer out of heaven didn't He?
It is much easier to post a Scriptural verse that explains a question, without a man's interpretation, since mankind tends to argue with what another PERSON says, when his argument is really with God, imo.
