God chose the sons and grandsons of Levi to serve Him in worship.  Why were some chosen and others not picked?  1 Chronicles 6:2

  God uses various people for His glory and purpose.  Why does He pick and choose?
  Because He is sovereign.  He has the ultimate, the supreme authority!

  Many kings and leaders of nations act like they are sovereign.  They don’t even come close to God’s sovereignty.

Consider this  ~

Psalm 103:19
“The LORD has established His throne in the heavens,
And His sovereignty rules over all.”

Where, in your life, do you need to accept God’s sovereignty?
