Dr. Jim Hamilton explains in his book Revelation: The Spirit Speaks to the Churches:
How will you fare before the wrath of God? Do you think status or influence or wealth or greatness is going to help you on that day? There is only one shelter from the wrath of God on that day-the shelter of the cross of Jesus Christ. Only those who believed that Jesus died to pay the penalty for their sins, that he rose to conquer sin and death, only those who trust Jesus will be sheltered by Jesus from divine wrath on that day.
Interestingly, the gospel is the great leveler of humanity in the same way that God's wrath is. The gospel declares that only Christ can save and that nothing you bring makes you closer to God. Money doesn't put you closer to God. Power doesn't, influence doesn't, greatness doesn't, freedom doesn't. The only thing that brings you closer to God is faith in Jesus Christ. Your pride will be demolished one way or the other. Do you want it demolished right now by the cross and the gospel, or do you want it demolished on the last day of the wrath of the lamb.
