........ And again that's where the political parties are divided.............
Yes, and I suppose division too because the tax payer is Not having a say as to how their money should be spent..
Of course government is necessary to maintain law and order in human society.
Christians obey secular law as long as obeying does Not require sin against God - Acts of the Apostles 5:29.
In other words, we are to be in a 'relative' position to God's 'absolute' position.
In the world today voting is often almost a 50/50 split so if one is on one side then the other side of voting people one has as their enemy.
Jesus did not try to change government in his day.
When the people wanted Jesus to hold political office Jesus simply ran away - see John 6:15 & John 18:36; John 17:16
Since Jesus did Not want to hold political office (king) then why would he instruct his followers to do otherwise.
To meddle with the secular political helps to divide people. Even sincere people who can't solve the problems.
Jesus kept his followers informed but Not to the point to get involved to operate in governmental affairs.
The work Jesus gave was Not political but 'spiritual' to tell others about God's kingdom being the solution.
God's kingdom standards is what a Christian explains, and how God's standards are followed in a Christian's life.
So, whether a secular law is: enacted, repealed or changed a Christian doesn't pressure others to agree.
By not pressuring then a Christian can speak to all others about the good news of God's Kingdom (Daniel 2:44) just as Jesus instructed his followers to do at Matthew 24:14; Acts of the Apostles 1:8.
Those who listen about God's kingdom (thy kingdom come) then will take up the Christian view as their life style.
