We speak because God has spoken.

Amos begins with a humble description of himself - "one of the sheep farmers" (Amos 1:1). Being a prophet of God has nothing to do with  what we are in ourselves. It's all about God. It's all about His grace and His call. Looking after sheep - This is such an apt description of the ministry of a pastor. "The Lord roars from Zion" (Amos 1:2). These words make us think of a lion. This could be terrifying for sheep. Think of the lion - Aslan - from "The Lion, the Witch and the Wardrobe" (C S Lewis). It's a picture of Christ. His voice is more than a roar. It's the voice of love. The "roar" speaks of authority. The greatest authority is the authority of love. How does the Lord command our respect? He loves us. As we learn to appreciate His love, we learn to love Him. Our love for Him is inspired by His love for us. As we learn to love Him, our obedience to Him increases in strength. "The Lord has said this" (Amos 1:15). The prophet's voice is to be an echo of the Lord's voice. We speak because God has spoken.
