Why me?

Isaiah 6:5
Then I said, “Woe is me, for I am ruined! Because I am a man of unclean lips, And I live among a people of unclean lips; For my eyes have seen the King, the Lord of hosts.”

Luke 11:5-8

Isaiah 6:6-8
Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs.
He touched my mouth with it and said, “Behold, this has touched your lips; and your iniquity is taken away and your sin is forgiven.”
Then 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!”
