As followers of Jesus we’ve been called in to His body in order to be sent out into the world with both gentleness AND courage. The only way to get the power to live on mission like that is to rejoice, not in power, not if gifting, not in your influence that we have, but rejoice that your name, of all names, is already written in heaven by the miraculous grace of God.
When your heart is resting in that reality, when the Lord asks you as He did Isaiah in chapter 6… “Whom shall I send, and who will go for us?” you’ll be able to say, “Here I am! Send me.”
