Amos was a blue-collar prophet. Unlike Samuel who grew up in the tabernacle and called as a child, Amos was called as a grown man who already had a vocation. Be careful about putting God’s calling in a box. You may think God does it this way or that. But He doesn’t do encores. And its never too late with God. After all, He called Moses at age 80! God calls whom He wills, when He wills, how He wills. Answering that call is ours to do. Yet, may I say that I have never seen anyone more miserable than the one called who declines. When God calls, hear and follow.
