We certainly have seen a Reformed resurgence and a recovery of the sovereignty of God to a certain extent. As strange as this may sound, I think the wrath of God is the most neglected attribute today. I think the doctrine of hell and preaching on hell have been forgotten by the church. That’s a reflection of the fact that we have lost sight of the wrath and the vengeance of God.
Another attribute that needs to be continually reintroduced is the aseity of God. Aseity refers to the sufficiency of God in Himself, which means that He has no needs outside of Himself. All of our needs are dependent upon Him. He is not dependent on anyone or anything.
Just off the top of my head, those attributes would be pretty high on the list.
