Not just the limitations of Government is a factor, but there are more serious hindrances - of which you dismiss.
Jesus said, there is a ruler of this world, and he has no part with that one.
(John 14:30) I will not speak with you much more, for
the ruler of the world is coming, and he has no hold on me.
Yet, you do not believe this one to be Satan the Devil. Yet all the Christian - followers of Christ, and his teachings - do. You don't even accept that Satan the Devil is a real entity.
(John 12:31) Now
there is a judging of this world; now the ruler of this world will be cast out.
Luke
(Luke 4:6) Then
the Devil said to him: “I will give you all this authority and their glory, because it has been handed over to me, and I give it to whomever I wish.
Paul
(2 Corinthians 4:4) . . .
the god of this system of things (age) has blinded the minds of the unbelievers, . . .
(Ephesians 6:11, 12)
11 Put on the complete suit of armor from God so that you may be able to stand firm against the crafty acts of the Devil;
12 because
we have a struggle, not against blood and flesh, but against the governments, against the authorities, against the world rulers of this darkness, against the wicked spirit forces in the heavenly places.
John
(1 John 5:19) We know that
we originate with God, but the whole world is lying in the power of the wicked one.
(Revelation 12:7-9)
7 And war broke out in heaven: Michael and his angels battled with the dragon, and the dragon and its angels battled
8 but they did not prevail, nor was a place found for them any longer in heaven.
9 So
down the great dragon was hurled, the original serpent, the one called Devil and Satan, who is misleading the entire inhabited earth; he was hurled down to the earth, and his angels were hurled down with him.
Those not keeping separate from the world, as Jesus did, and prayed, and commanded his followers, are all under the rule and authority of the ruler of this world.
For this reason, the Bible "says" that these sleepers will have a "rude awakening" - a grave disappointment indeed.
(1 Thessalonians 5:2-6)
2 For
you yourselves know very well that Jehovah’s day is coming exactly as a thief in the night. 3 Whenever it is that they are saying, “Peace and security!” then sudden destruction is to be instantly on them, just like birth pains on a pregnant woman, and they will by no means escape. 4 But you, brothers, you are not in darkness, so that the day should overtake you as it would thieves,
5 for you are all sons of light and sons of day. We belong neither to night nor to darkness.
6 So, then, let us not sleep on as the rest do, but let us stay awake and keep our senses.
God's servants - the faithful followers of Christ - true Christians - busy themselves in the work Jesus assigned them to - that of declaring the good news of God's kingdom, as a witness to all the nations, before the end comes. Matthew 24:14
(Romans 10:11-15)
11 For the scripture says: “No one who rests his faith on him will be disappointed.”
12 For there is no distinction between Jew and Greek. There is the same Lord over all, who is rich toward all those calling on him.
13 For “everyone who calls on the name of Jehovah will be saved.”
14 However, how will they call on him if they have not put faith in him? How, in turn, will they put faith in him about whom they have not heard? How, in turn, will they hear without someone to preach? 15 How, in turn, will they preach unless they have been sent out? Just as it is written: “How beautiful are the feet of those who declare good news of good things!”
Hence, Psalms 146
Rather than getting involved in this world, the Christian seek to help save people from the calamity to come upon the world. It is coming, according to Daniel 2:44
It's evident that trying to patch, fix, or save this corrupt dying system, is like trying to fill a bag full of holes, with grain.
Is it not?
Does taking sides of the kings of the inhabited earth, puts us in opposition to the king of God's kingdom.
(Revelation 16:13-16)
13 And I saw three unclean inspired expressions that looked like frogs come out of the mouth of the dragon and out of the mouth of the wild beast and out of the mouth of the false prophet.
14 They are, in fact, expressions inspired by demons and they perform signs, and they go out to the kings of the entire inhabited earth, to gather them together to the war of the great day of God the Almighty.
15 “Look! I am coming as a thief. Happy is the one who stays awake and keeps his outer garments, so that he may not walk naked and people look upon his shamefulness.”
16 And they gathered them together to the place that is called in Hebrew Armageddon.
The government the Christian supports is not man-made, but it is the government set up in heaven, with God's appointed king. Psalms 2.
This is the government that will last forever, and solve all man's problems... permanently. Will you not support it?
