He said, "Praise the name of God forever and ever, for he has all wisdom and power. He controls the course of world events; he removes kings and sets up other kings. He gives wisdom to the wise and knowledge to the scholars." (Daniel 2:20, 21 NLT)
Just so you know...the ultimate authority in choosing world leaders is the God of Heaven. We need to pray that God will give us the leadership we need, not what we deserve. After talking with God about it then go cast your vote, leaving the outcome to the One that "controls the course of world events."
