1 Thessalonians 4:14
For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him. (1 Thessalonians 4:14)
13,14 Errors Regarding Christ’s Coming
 There was still another reason for Paul’s communication to these brethren. Some who were newly brought into the faith had fallen into errors in regard to those who had died since their conversion. They had hoped that all would witness the second coming of Christ; but they were in great sorrow as one after another of the believers fell under the power of death, making it impossible for them to behold that desirable event—the coming of Christ in the clouds of heaven.
 Some, who had fallen into the error that Christ was to come in their day, imbibed the fanatical idea that it was praiseworthy to show their faith by giving up all business, and resigning themselves to idle waiting for the great event which they thought was near (Sketches from the Life of Paul, 110).
