Read Part 1.
If we take a look at 1 Thessalonians 4:13-17 we can try and track what the apostle is teaching:
But I do not want you to be ignorant, brethren, concerning those who have fallen asleep, lest you sorrow as others who have no hope. (1 Thess. 4:13)
Paul’s concern is that the embattled believers at Thessalonica are not unaware of a certain doctrine concerning those saints who have passed since it will give them hope.
