Daniel 2:21 (NIV)
He changes times and seasons; he sets up kings and deposes them. He gives wisdom to the wise and knowledge to the discerning.
Romans 13:1-5 (NIV)
1Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God.
2Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.
3For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and he will commend you.
4For he is God’s servant to do you good. But if you do wrong, be afraid, for he does not bear the sword for nothing. He is God’s servant, an agent of wrath to bring punishment on the wrongdoer.
5Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also because of conscience.
Matthew 22:37-39 (NIV)
37Jesus replied: ” ‘Love the Lord your God with all your heart and with all your soul and with all your mind.’
38This is the first and greatest commandment.
39And the second is like it: ‘Love your neighbor as yourself.’
