How Do You Pray for the Lost?

How do you pray for those who have not believed the gospel? I'm guessing you do pray for these friends, relatives and neighbors, but how do you pray? Do you simply offer up the prayer that God would save them, or do you seek God's work more specifically? Are you praying...

Prayer for the lost should be more than a hail mary pass to our father in heaven. Be specific. Ask God to do what only he can do. And as we pray let's make every effort to share the gospel with them as well.
