"God called unto him...and he said, Here am I" Exodus 3:4
When God speaks, many of us are like men in a fog, we give no answer. Moses' reply revealed that he was somewhere. Readiness means a right relationship to God and a knowledge of where we are at present. We are so busy telling God where we would like to go. The man or woman who is ready for God and His work is the one who carries off the prize when the summons comes. We wait with the idea of some great opportunity, something sensational, and when it comes we are quick to cry - "Here am I." Whenever Jesus Christ is in the ascendant, we are there, but we are not ready for an obscure duty.
Readiness for God means that we are ready to do the tiniest little thing or the great big thing, it makes no difference. We have no choice in what we want to do, whatever God's program may be we are there, ready. When any duty presents itself we hear God's voice as Our Lord heard His Father's voice, and we are ready for it with all the alertness of our love for Him. Jesus Christ expects to do with us as His Father did with Him. He can put us where He likes, in pleasant duties or in mean duties, because the union is that of the Father and Himself. "That they may be one, even as We are one."
Be ready for the sudden surprise visits of God. A ready person never needs to get ready. Think of the time we waste trying to get ready when God has called! The burning bush is a symbol of everything that surrounds the ready soul, it is ablaze with the presence of God.
