The Bible clearly defines the following as ministries of the church: worshiping the living God, instructing and edifying believers, making disciples of all nations, and serving the needy.
Excerpt from InTouch Ministries Daily Devotional
23 Let us hold tightly without wavering to the hope we affirm, for God can be trusted to keep his promise. 24 Let us think of ways to motivate one another to acts of love and good works. 25 And let us not neglect our meeting together, as some people do, but encourage one another, especially now that the day of his return is drawing near. Hebrews 10:23-25 (NLT)
