Your sky god is no more help to you than he is to any other boxer. Believing in Christ won't make much difference to anything other than your own state of mind.
Ole JC won't be walking into Mayweather's right hand leads. Maybe your faith will help you get through a few more before snapping like Ortiz did, but unless Floyd gets old in the ring I can't see the windmill that fought Berto being able to lay a glove on Mayweather.
Don't get me wrong, I think Mayweather is a c*nt; but he's a c*nt with elite skills and won't stand there whilst you maul him on the ropes.
