"God can use you if you're willing"

Here. Every Christian has at least one ministry.

But each of us was given grace according to the measure of Christ’s gift. ⁸Therefore it is said, “When he ascended on high he made captivity itself a captive; he gave gifts to his people.” ⁹(When it says, “He ascended,” what does it mean but that he had also descended into the lower parts of the earth? ¹⁰He who descended is the same one who ascended far above all the heavens, so that he might fill all things.) ¹¹The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, ¹²to equip the saints for the work of ministry, for building up the body of Christ, ¹³until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ. (Ephesians 4:7-13)
