In order to catch or attract people's attention, it may be necessary to employ some kind of dramatic or spectacular tactics.
So, a big show with bright lights and loud sounds would certainly make people turn their heads as well as get their attention.
But the 1st reading tells us the mystery and presence of God is nothing known to our senses: not a blazing fire, or a gloom turning to total darkness, or a storm, or trumpeting thunder or some loud noise.
Like how the prophet Elijah experienced the presence of God in the sound of a gentle breeze, the mystery and presence of God is often found in the simple and humble.
As Jesus sent out the Twelve in pairs, He gave them authority over the unclean spirits and almost nothing else.
They had nothing to attract the people's attention, and in fact they had to be so simple and ordinary that they can be easily written off.
But with the authority from Jesus and with the power of God working in them, they set off to preach repentance and they cast out many devils and anointed sick people with oil and cured them.
Let us learn how to be simple and humble in our lives. It is through simplicity and humility that God will empower us to proclaim the Good News with our lives.
