2 kings 15: 3He did what was pleasing in the lord’s sight, just as his father, Amaziah, had done. 4But he did not destroy the pagan shrines, and the people still offered sacrifices and burned incense there. 5The lord struck the king with leprosy, which lasted until the day he died. He lived in isolation in a separate house. The king’s son Jotham was put in charge of the royal palace, and he governed the people of the land.

Uzziah was pleasing to God.. why then would God strike him with leprosy and cause him to be separated.. living in isolation?

I think we really don't know God.. we see God as someone who does all that we want Him to do... plans out our lives in ways to make us happy everyday.. having everything we want... 

well I think we need to read the old testament as much as we read the new testament... we need to see that everything God does is for the good and the furthering of His kingdom.. now what we want or think or desire.. 

God loves you every day.. more than you love yourself even.. but that is not going to make everything easy and happy... not always.. and sometime.. depending on His plan for you specifically.. it might never be that way... but it is still for your good.. to make you the person He created you to be.. to fulfill the plan that He has for your life in His kingdom... 

so how was the leprosy for Uzziah's good? possibly the whole purpose was so that others who read the bible can see that life is not always easy.. we are not always healed.. we are not always prosperous.. we are not always what we want to be.. but we are always exactly what God planned out for us to be.. and because of what our purpose is.. others can look at our lives and see something in their own lives of value too... 

we always live for someone else's benefit.. and God will work out His perfect will and purpose in our lives.. every time..
