 When you consider our sin against God, when you consider the wickedness that dwells within your own heart, your sin against Him, God's wrath poured out against you for your sin is a measured, proportionate, appropriate, fitting response. God considers the depth of our sin, He considers that we would rather worship ourselves than to glorify Him as God and to be thankful, and He concludes that a measured response, a proportionate response, an appropriate response to that rejection is divine wrath.
