Jesus, in Luke , makes a very interesting statement…one that provides a perspective on faithfulness you would not expect,
"And if you have not been faithful in what is another man's, who will give you what is your own?"
Jesus makes it clear. You have to be faithful in something that is someone else's before He will fulfill your dream or open doors for you.
God gives each of us opportunities to help others. And He looks for us to faithfully help others before He blesses us. For example, Joseph had to help Pharaoh with his dream, before God allowed Joseph's dream to come to pass.
Maybe you have a dream to be super rich for the purpose of spreading the gospel. You would like to see the gospel go around the world. Or you would like to pay off the debt on your church's building. Or you would like to fund a certain missions organization.
I think the Kingdom could use a multitude of very wealthy people who have a heart for the lost and a desire to see God's work succeed and expand.
But first you need to be faithful working for that person who has hired you. You have to be faithful in that which is another man's. God is not going to open a door for you to fulfill the dream you have if you do not show up for work on time, or if you do not put in a full day's work. Why would God open the door for you to lead your own successful business if you have not been faithful working for someone else?
You must serve that other person with all of your heart, or that other company you are working for first, before God will prosper you. It is a Kingdom principle.
