"We cannot be safe if we be secure. It concerns us at all times, but especially at some times, to be very cautious." (Matthew Henry) As one of His disciples, Jesus is warning you to watch against the prevailing love of ease and the selfishness of the age (that would be prevalent in the days before His return) lest you tread in the world's footsteps. He is warning you against two (2) dangerous sins - voluptuousness and earthly-mindedness - which would most certainly prevent you from being prepared for His coming. Watch over yourself very carefully! Can you hear His warning?
