It is like a man travelling abroad:he has gone from home, and left his servants in charge, each with his own task; and he has told the doorkeeper to stay awake!
Three points: Stay awake, I am in charge, Do my task!
To stay awake is to feel the ardent desire to be at the presence of the Lord who is molding the clay. Feel that you are the work of His Hand (first reading)
I am in charge of what: of all the graces I have received through Jesus Christ. So, don’t stop thanking the Lord in prayers and witnessing. (second reading)
Each one with his own task: That is to respect the task of each one and to help the other with his or her task. Each task is important as it is entrusted by Lord.
