What does the Bible say about God's calling of ministers?

In the Bible, particularly in the New Testament, we see that God commands His chosen individuals to follow Him and serve as ministers. For instance, Jesus called His disciples with the directive 'Follow me' (Matthew 4:19), emphasizing that this calling is not merely a suggestion but a divine mandate. This reflects God's sovereign authority in selecting His ambassadors, much like in the Old Testament where figures like Jephthah acted as God’s representatives (Judges 11:12-28). The ministry is exclusively God's prerogative, and man cannot presume to call someone into it without God's clear direction.
