For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. 1 Thessalonians Efforts to determine the date of Christ's return are foolish. Don't be mislead by anyone who claims to know. We are told in scripture that no one knows. Even believers will be surprised. The Lord will return suddenly and unexpectedly, warns Paul, so be ready because no one knows when Jesus will come back to earth to take every Born again believer out of this world. We should be ready at all times. How do you get ready ? Simply repent and ask Jesus Christ into your Heart and life. Romans
