Walking in the Strength of the Lord

I know that  I don't walk in my own strength, because on my own there is no way that I could go sub.  I always thought that was the scariest thought of all teaching possibilities.  But, here I am, off to do it.  Hope I have everything.  Probably don't.  That's ok.  Good teachers know how to make things work.  And, I am a good teacher.  I want to be excellent.  In time.
grace to you.
