But the Lord took me from tending the flock and said to me,

                 ‘Go, prophesy to My people Israel.’ ”

                                  (Amos 7:15)

The people are asking, “Who is this rustic farmer that he should preach to us and claim to be God’s prophet? What kind of authority does he think he has?” Now, if an uneducated rustic farmer is preaching God’s Word, it means that God Himself has called him. Preaching is not a vocation that Amos would have chosen for himself; instead, it’s chosen for him by the Lord. When a prophet proclaims God’s Word, it’s because God is about to do something important and wants to warn His people.
