The occasion of Jesus' Second Coming, identified in the Bible as the Day of the Lord, will be one of the greatest days in history. But it's important to focus on identifying the recognizable sign of His return instead of the unknowable day. (Mat. 24:27-36). By associating that day with 24 dramatic biblical events and 54 vivid prophetic images, author David S. Heeren zeroes in on the sign and discloses its potential as the tool for an eon-ending revival that could involve the salvation of thousands or even millions of people (Joel 3:14).
