The following is an amazing statement about the calling of God in our lives. It is better to be still and listen; than, too shout and never be heard.
Isaiah was so attuned to God, because of the great crisis he had just endured, that the call of God penetrated his soul. The majority of us cannot hear anything but ourselves. And we cannot hear anything God says. But to be brought to the place where we can hear the call of God is to be profoundly changed.
ISA 6:8 ESV
And I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” Then I said, “Here I am! Send me.”
