After John sees a vision of the last day, the sun turning dark and the mood blood red, the stars falling from the sky, the question is asked "Who can stand?" Who can stand before the judgment throne of God? No one can on their own, by their own power, on the basis of what they have or have not done. All have sinned and deserve the wrath of the Lamb. But God provides John, and us, comfort. He shows him that before the judgment comes, those who belong to God through faith in Jesus are sealed for safety. Are you sealed for safety on the day of judgment? Look to your Baptism, look to the Lord's Supper, look to the objective promises of God that he has redeemed you. You belong to him. He has marked you with is seal.
