The flock is a biblical image for God's people.
Just as sheep depend upon a shepherd for guidance, protection, and provision, believers depend upon Christ and the spiritual care provided within the church.
Scripture frequently describes the church as a flock, Christ as the Good Shepherd, and church leaders as under-shepherds who care for those entrusted to them. The image emphasizes both the responsibility of leaders and the dependence of believers upon God's care.
See in Scripture: Psalm 100:3; John 10:1–18; Acts 20:28; 1 Peter 5:2–4
