Jeremiah 1:6-7
Then said I:
“Ah, Lord God!
Behold, I cannot speak, for I am a youth.”
But the Lord said to me:
“Do not say, ‘I am a youth,’
For you shall go to all to whom I send you,
And whatever I command you, you shall speak.

Jeremiah is reluctant to accept the post of prophet. His excuse is his age. Moses had five excuses that did him no good. It won’t work for Jeremiah either.
The Lord assures him He has put His words in his mouth.
I’m not sure if it’s standard procedure, but I fought God’s calling as a minister on my life. I was quite young too, only eighteen at the time.
Before that, I was actually reluctant about salvation but I’m so glad I took that step and the next of ministry.
One advantage I have over Jeremiah is my ministry helper – my wife, who really had her own ministry calling.
We compliment each other as pastors of a church and as husband and wife outside the church.
