Yes, Bible-believing, conservative Christians should preach about the importance of having Bible-believing Christians as elected officials.
It is a very important priority for Bible-believing conservative churches to produce good, Bible-believing politicians in their local communities and in their state. There is no educational requirement to hold political office. Any US citizen can run for office.
Bible-believing Christians should bravely run for political office in order to support Bible-based morality in their local community and in their state. It is a very important Christian work.
Salary pay for politicians is good, middle class salary, so it is worth working as an elected official even from a financial standpointC. And if you are good in local politics, you can enter county or state politics. You may even work up to national politics, such as becoming a US Senator.
It is the duty of Bible-believing Christian pastors to produce Christian politicians in their local community and in their state, who will follow the Bible not only in personal affairs but also in political business.
Every political decision affects Christians in one way or another.
