God works every day to bring people to himself. Jesus said both he and the Father were working (John 5:17). The Father seeks true worshippers (John 4:23). In the parable of the prodigal son, the father was watching down the road for his son. God is actively drawing people to himself. So, we pray, and make ourselves available to do what God wants. Our prayers ask God to work for others, and also to show us how we can take part.
