Seek the welfare of the city where I have sent you into exile, and pray to the Lord on its behalf; for in its welfare you will have welfare (Jer. 29:7).
It is certainly understandable why many genuine Christians, in centuries past, have felt that holding political office was incompatible with following Christ. If a government, for example, prohibits Christians from holding public office, thus requiring them to renounce their faith in the Lord Jesus Christ in order to serve, it is obvious that God would not want any of His children to make that compromise.
