"Gird up the loins of your mind" What???

Is that Scripture's way of saying get some cajones?  :)

One of the things we intentionally taught our kids was mental toughness. 

Here is just one example of how that paid off.  My youngest son Jed was pitching in a Little League game.  I think he was 11.  There were two adults on the other teams sideline just mercilessly verbally harrassing my son.  So much so that the home plate umpire called time and went over and told them to knock it off. 

The thing is, the harassment didn't bother Jed at all.  He had a smile on his face and just kept pitching, and pitching well.  What the umpire didn't know was that the two adults who were harassing him were two of his travel ball coaches.  They knew he was mentally tough enough to take it! (Yeah, that was a proud Pappa moment :)

So I ran across this verse this morning and it seems to be preaching mental toughness although with some strange wording. 
 

1 Peter 1:13(NKJV)

Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; 

 

Loins of your mind?  I don't know about you but with the reference to the loins it seems to me that Peter was telling people to get some mental cajones or in other words get some mental toughness. 

Pretty cool!
