Orderly and Obedient by Gloria Hass
"And he said unto them, Behold, when ye are entered into the city, there shall a man meet you, bearing a pitcher of water; follow him into the house where he entereth in." Luke 22:10
Jesus had specific instructions for Peter and John for the eating of the Passover meal. All the details were lined up in a specific and orderly manner which is no different than what God does for you and me.
Peter and John were expected to follow Jesus' exact instructions. They weren't to add to it or decide not to do some things because they I'm didn't feel like it.
Regardless of how small and unimportant a task you might think you are required to do, God thinks of every task as important. God has a purpose for everything. It's important for us to realize this and to be obedient as to what God tells us to do regardless of our feelings or thoughts.
