He used the language and imagery of anger and wrath. So for us fear can play a role in our faith or our concept of God. The Lord can use our fear to keep us loyal to Him. But how He does that is the next question we need to discuss. Another way of saying this is that our concept of the Lord changes with regeneration or spiritual progress, and with it, the character of our fear of God.
Regeneration is a complete change.
This change is compared to the growth of a tree in the Word. If we observe a tree from day to day, we do not notice much change. But if we expand our view to the whole life of the tree, we will see that it has changed completely. It began as a little sapling, and grew into a huge tree with many branches, twigs, and leaves. As the Lord transforms us, our concept of Him undergoes a complete change as well.
