The believer should be active in serving Christ during these last days, all the while anticipating the imminent, pre- millennial return of Christ for His church. At that time, the dead in Christ shall be raised in glorified bodies, and the living in Christ shall be caught up to meet the Lord in the air. This will occur before the seven-year tribulation period begins. (1 Thessalonians 4:13-18; 1 Corinthians 15:42-44; Philippians 3:20-21)
