Authority Behind the Great Commission

Many of us can quote the Great Commission, Matthew 28:19-20.  But, notice verse 18.  "All authority is given to me (Jesus.)" 

The power of the Great Commission lies in the one who gave us the charge, Jesus.  He has all authority.  Not just a little. 

And He promised

1. The gates of Hell shall not prevail against the church.
2. I will be with you always.

With these two promises, given to us by the one who has all authority, do we really have any reason to fear failure?  Any reason to fear anything?  No and no.
