Luke 12

“And do not seek what you should eat or what you should drink, nor have an anxious mind.  For all these things the nations of the world seek after, and your Father knows that you need these things.  But seek the kingdom of God, and all these things shall be added to you." vv.29-31

Read chapter 12
What makes you anxious?  What are you most afraid of today?
Eating and drinking are man's most basic needs and in many countries and all cities wondering when you'll have your next meal is a normal thought unlike many of us today in the United States.  We do have to remember that Jesus was talking specifically to the twelve disciples (verse 22) while they were to go around and proclaim the Kingdom of God.  In this they would be provided for with food and drink by what God would work out from who and when; kind of like if one goes on a business trip the company usually provides for all the lodging and meals you just have to go.  But we today can still take from these commands.  The world's basic needs don't go unnoticed by the Father although many would say so looking at the world today.  His Kingdom is not on earth now and until His government is ruling the world we will have hunger and poverty.  We are to seek first His kingdom over focusing on things that cause anxiety in us.  Yet what does it look like or mean to seek first His Kingdom?  Since the Kingdom is not here on earth today we can't just stumble upon it.  But we can seek to know what God's Kingdom is in the Bible He's given to us.  Throughout all of scripture the Kingdom of God is preached and a reality that is soon to come as we wait for His return.  The more we seek and desire more of Him the cares of this world diminish and increases our joy.  
So when problems arise what is your first response?  Is it get overwhelmed, worry, anger, fuss?  Try to make your natural response become one to pray first to the Father that knows all things you need.
