Also I heard the voice of the Lord, saying: “Whom shall I send, And who will go for Us?” Then I said, “Here am I! Send me.” – Isaiah 6:8 NKJV
Isaiah had a lot of courage to volunteer to deliver God’s messages.
Sometimes when God calls us to do something, we try to look the other way because what He is asking us to do is difficult. The task might include forgiving someone who has wronged us. It might include speaking the truth, even if nobody wants to hear it. It might include relinquishing control to God, who does a better job at managing things than we are capable of doing.
Nobody is perfect except God. Amen.
