"No one who looks back is fit for the kingdom of God"

Scripture: Luke 9:57-62

With the call the Lord gives the grace to respond and the strength to follow all the way to the end. Why does Jesus issue a challenge with the call? Jesus was utterly honest in telling people what it would cost to follow him. When a would-be disciple approached Jesus and said he was ready to follow, Jesus told him it would require sacrifice.We are free to decide whether we will take the path which Jesus offers. But if we choose to go, then the Lord wants us to count the cost and choose for it freely.
What does the story of a plowman have to do with the journey? A plowman who looked back while plowing caused his furrow to be crooked. He had to look straight ahead in order to keep the plow from going off course. Likewise, if we look back on what we have freely left behind to follow the Lord, our path will likely diverge and we'll miss what God has for us.
