The Lord Jesus taught the Christians to pray, “Thy Kingdom Come, Thy will be done on earth.” Does that mean that all Christian people should join together and vote for the election of only Christian men to office in order that the will of God might be done on the earth?

The true footstep followers of the Lord Jesus are called to a "heavenly calling" (`Heb. 3:1`), to the "high calling of God" (`Phil. 3:13`.) They are running for the office of joint heirship with Christ Jesus in His Kingdom. The Apostle Paul was one of these runners. He realized that a man cannot well run for two offices at the same time. He said, "Do not be conformed to this world." (`Rom. 12:2`.) That is to say, do not become entangled with the things of this world. Again he said, "This one thing I do, forgetting those things which are behind and reaching forth unto those things which are before, I press toward the mark for the prize of the high calling of God in Christ Jesus" (`Phil. 3:13,14`); and in harmony with this Jesus said, "Ye are not of this world"; and again, "My kingdom is not of this world," meaning this present evil order of things; therefore we come to the conclusion that the chief duty of the Christian is to avoid entangling alliance with worldly systems, and to devote himself to preparing for the kingdom of our Lord when He comes. All good citizens should desire righteous men in office, but a righteous government cannot be established by imperfect men, hence the hope of the Christian is in the Bible teaching that Christ Jesus, the great Messiah, will, in God's due time, set up His kingdom, and establish righteousness in the earth.
