"Water cooler" employees eventually lose their jobs. I have seen far too many fellow workers fired because they failed to do their work. They were given a task to fulfill and they stood around and talked the day away. The employer was left with unmet deadlines and twice the work for the next day. Blessed is the person who is found working when the boss comes around.
The Lord knew that there would be a number of "water cooler" people who would attend church and live within the Christian community. There is much work to do for the Kingdom of God, but alas, many people would rather sit by and watch. A true and faithful servant of Jesus is one who walks the walk rather than just talks the talk.
Are you a talker or a doer my friend? Would you appreciate someone working for you that just passed the time of day? Of course not. How do you believe the Lord feels when you talk more than work? Remember the words of Solomon in Ecclesiastes 9:10, "Whatever your hand finds to do, do it with your might..." Blessed is the person who is found working when the boss comes around.
