Become What You Believe

So, I signed up for daily Bible readings to be sent to me via email.  Part of my reading this morning was this:

Then he touched their eyes and said, “According to your faith will it be done to you”;  and their sight was restored.  Matthew 9:29-30  NIV

 A different version reads like this: 

He touched their eyes and said, "Become what you believe." It happened. They saw.  Matthew 9:29-30 The Message

I often struggle with what I believe.  Lord, help my unbelief, so I can become what you want me to be.
