Revelation 11

13 At that very hour there was a severe earthquake and a tenth of the city collapsed. Seven thousand people were killed in the earthquake, and the survivors were terrified and gave glory to the God of heaven.
This is a somewhat an abnormal and rare reaction from pagans/unbelievers as it is usually those who are Christians who typically praise God despite a personal tragedy or hardship takes place. It seems that these people have either acknowledged God's power or repented for their hedonistic lives. This pleases God as He loves to be glorified, I wish I could certainly act like I've repented as I'm still tainted in my speech, pride, view of women, view spiritual elitism. Glorifying Him should prompt me to moral action and genuine service.
