Jeremiah 1:6-8 NIV

[6] “Alas, Sovereign LORD,” I said, “I do not know how to speak; I am too young.” [7] But the LORD said to me, “Do not say, ‘I am too young.’ You must go to everyone I send you to and say whatever I command you. [8] Do not be afraid of them, for I am with you and will rescue you,” declares the LORD.
