Romans 8:28

And we know (with great confidence) that God (who is deeply concerned about us) causes all things to work together (as a plan) for good for those who love God, to those who are called according to His plan and purpose.  

We can have confidence in God and His plan for His people.  When God made us, He gifted us to help complete His plans for this world.  The world will continue to go around, and the devil will never stop Jesus from coming back.  We can have confidence and faith in God.
