When and where are you most likely to receive instructions from God about what he would like you to do?
I rather suspect that the most common reply to that question would indicate praying as the activity most inclined to make us aware of God's purpose for us, but the story of the Bible suggests otherwise.
Moses heard God’s call when he was tending his family's sheep, as did David, and probably Amos. Gideon heard it when threshing grain. Elisha while ploughing a field. Peter, Andrew, James & John were called by Jesus while fishing. All these people were called into God’s service while they were at work. Isaiah may seem like an exception; he saw a vision of God while he was in the temple. But Isaiah wasn’t there for his personal devotions. He was a priest. He was at work.
There’s a definite pattern here. In almost all the Bible stories of people being called by God to do a particular task, that calling took place when they were at work. Jacob and Elijah are an exception - they were running away from trouble. Samuel and Jeremiah were only children at the time, and Paul was busy hunting down Christians.
It almost seems that the message from God is, “Don’t call me; I’ll call you.”
Our primary calling in life is to work hard for our families and our communities. By carefully serving those around, we serve God. If there’s something extra that God needs us to do - he will let us know.
Consider yourself to be on-call.
