Romans 11:25: The Rapture is imminent; it could happen immediately.
Titus 2:12 and 13: We should be living our lives in the full anticipation that Christ could come for us at any time.
I Corinthians 15:51-53: The Rapture of the Church is a wholly Pauline revelation, only found in Paul’s writings alone. It is in sharp contrast with the Second Coming of Christ, which has been foretold by all the prophets since the world began (Acts 3:19-21). They are two distinct events, separated by at least seven years.
