MISSION IMPOSSIBLE ?

Jeremiah 1:4-8(NIV)
The Call of Jeremiah
4The word of the Lord came to me, saying,
5“Before I formed you in the womb I knew you,
before you were born I set you apart;
I appointed you as a prophet to the nations.”
6“Alas, Sovereign Lord,” I said, “I do not know how to speak; I am too young.”
7But the Lordsaid to me, “Do not say, ‘I am too young.’ You must go to everyone I send you to and say whatever I command you. 8Do not be afraid of them, for I am with you and will rescue you,” declares the Lord.

Isaiah 49:1-6(NIV)
The Servant of the Lord
1Listen to me, you islands;
hear this, you distant nations:
Before I was born the Lord called me;
from my mother’s womb he has spoken my name.
2He made my mouth like a sharpened sword,
in the shadow of his hand he hid me;
he made me into a polished arrow
and concealed me in his quiver.
3He said to me, “You are my servant,
Israel, in whom I will display my splendor.”
4But I said, “I have labored in vain;
I have spent my strength for nothing at all.
Yet what is due me is in the Lord’s hand,
and my reward is with my God.”
5And now the Lord says—
he who formed me in the womb to be his servant
to bring Jacob back to him
and gather Israel to himself,
for I am honored in the eyes of the Lord
and my God has been my strength—
6he says:
“It is too small a thing for you to be my servant
to restore the tribes of Jacob
and bring back those of Israel I have kept.
I will also make you a light for the Gentiles,
that my salvation may reach to the ends of the earth.”
