“Therefore let us not sleep, as others do, but let us watch and be sober.” I Thessalonians 5:6. When we believe a warning, it affects our behavior. It’s true in every area of life, including our walk of faith. Paul wrote to the Christians in Thessalonica, reminding them that the day of the Lord would come unexpectedly. His call to action urged them to avoid spiritual lethargy while remaining alert and self-controlled. Jesus also urged his followers to be watchful and ready for His second coming. If we believe our Lord’s word about His coming, how will it affect our thoughts and actions today? Every Christian should be an expectant up-looker, not a sleepy onlooker.
