Call to Missions

This is my call to missions:
Now the word of the LORD came to me saying,
"Before I formed you in the womb I knew you,
And before you were born I consecrated you;
I have appointed you a prophet to the nations."
Then I said, "Alas, Lord GOD!
Behold, I do not know how to speak,
Because I am a youth."
But the LORD said to me,
"Do not say, 'I am a youth,'
Because everywhere I send you, you shall go,
And all that I command you, you shall speak.
"Do not be afraid of them,
For I am with you to deliver you," declares the LORD.

Jeremiah 1:4-9
