Dr JT Lee is talking about the day of the Lord. In 1 Thessalonians 5:2-3, the day of the Lord comes as a thief which is same expression of coming Jesus in the Book of Revelation. Because the day of the Lord is coming as a thief, it will not happen any days that people are expecting. Dr JT Lee's wife, Gloria heard from God recently that there would be no tsunami in September in this year. We have to be ready for His coming at all times. Please do not wait for certain days. He is coming for the holy and blameless brides according to Ephesian 5:23.
