What does the Bible say about God calling prophets?

In 1 Kings 19:16, God commands Elijah to anoint Elisha as his successor, illustrating God's sovereign choice in appointing leaders and prophets. This demonstrates that God selects His instruments without regard for human expectations or merit. Elisha's calling is a vivid depiction of God's grace, as he was chosen to serve before he was even aware of it. This aligns with God’s pattern of appointing individuals according to His sovereign will, highlighting that the ministry is not a human endeavor but a divine appointment.
