What is your specific ministry?
That which you learn especially from the Lord, that which you specifically receive from Him.
No No No!!! it is NOT what you learned nor received from the world.
No No No!!! it is NOT all your so called abilities and talents you gathered and learned during your unbelieving days, and that now as a Christian believer that God is going to use you and them. No No No!!!
Only what comes from Above is able to make for the Increase of the Body.
Each member needs to seek earnestly from the Lord.
