From John 9:2-3:

And His disciples asked Him, "Rabbi, who sinned, this man or his parents, that he would be born blind?"  Jesus answered, "It was neither that this man sinned, nor his parents; but it was so that the works of God might be displayed in him." 

I was reminded again as I read this last night that everything is about God.  This man had endured blindness for who knows how many years, but it wasn't for nothing; it was for the noblest of all causes--to display the glory and power of God.  How much easier it is to endure everything when we remember that it's the glory of God that matters most (more than our comfort or even our lives), and that our sufferings for His glory are worth it because of what they accomplish for His plan!  When seen this way, we can embrace them as our duty and willing service and submit to them "for the joy set before us" both now and in the end.
