Ephesians 6:12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
The 'principalities and powers and rulers of the darkness of this world’ are the political and religious governments of this world which rule in ignorance of the truth.
NKJV Ephesians 3:10 to the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places,
The decision of the Jewish rulers and Roman Governor to put Jesus to death was overridden by God who raised him from the dead on the third day. His resurrection was an indisputable fact. At his resurrection he was given jurisdiction in heaven and earth.
Colossians 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Matthew 28:18... All power is given unto me in heaven and in earth.
His disciples are to be subject to worldly governments as long as their rules do not conflict with the commandments of God.
Titus 3:1 Put them in mind to be subject to principalities and powers, to obey magistrates, to be ready to every good work,
Though the governments be evil, they are nonetheless put in place by God to bring about his intended purpose.
Romans 13:1 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God. 2 Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation. 3 For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same: 4 For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil. 5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake. 6 For for this cause pay ye tribute also: for they are God’s ministers, attending continually upon this very thing.
Jesus was the light of this world in that he taught by word and example what God requires men and women to do if they would attain unto eternal life in the kingdom of God.
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
The gospel of the kingdom of God was not to be imposed throughout the world by the sword (we wrestle not against flesh and blood), but be spread by the ‘foolishness of preaching’.
2 Corinthians 10:3 For though we walk in the flesh, we do not war after the flesh: 4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
1 Corinthians 1:21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
In time, pagan idolatry in the Roman world was supplanted by a general belief in the one true God and laws were changed accordingly. Not that the political and religious governments were fully enlightened; that will not happen until Christ returns. Force will be required to convince them.
Psalm 2:1 Why do the heathen rage, and the people imagine a vain thing? 2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, saying, 3 Let us break their bands asunder, and cast away their cords from us. 4 He that sitteth in the heavens shall laugh: the Lord shall have them in derision. 5 Then shall he speak unto them in his wrath, and vex them in his sore displeasure. 6 Yet have I set my king upon my holy hill of Zion. 7 I will declare the decree: the LORD hath said unto me, Thou art my Son; this day have I begotten thee. 8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession. 9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel. 10 Be wise now therefore, O ye kings: be instructed, ye judges of the earth. 11 Serve the LORD with fear, and rejoice with trembling. 12 Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
