IT'S ENOUGH

Well old Paul and Silas were thrown in jail
They had nobody to go their bail
They told that old jailer our salvation plan
It was good enough to save that old jailer man.

  It's enough
                It's enough to make us shout and sing
  It's enough
               It's enough to make the heavens ring
  It's enough
               It's enough to take a soul away
  It's enough
               It's enough to take us home some day


Well I went to a meeting the other night
I knew what the preacher was talking about
He told of a man who died on Calvary
That was good enough to save an old boy like me.

  Chorus several times
