He's not a liberal - that's an ignorant assumption, or a narrative being pushed by those with socialist agenda, or by Liberal Christians!
2 Corinthians 6:14
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?

Ezra 7
25 And thou, Ezra, after the wisdom of thy God, that is in thine hand, set magistrates and judges, which may judge all the people that are beyond the river, all such as know the laws of thy God; and teach ye them that know them not.
26 And whosoever will not do the law of thy God, and the law of the king, let judgment be executed speedily upon him, whether it be unto death, or to banishment, or to confiscation of goods, or to imprisonment.
Proverbs 24
5 A wise man is strong; yea, a man of knowledge increaseth strength.
6 For by wise counsel thou shalt make thy war: and in multitude of counsellors there is safety.
Proverbs 24
10 If thou faint in the day of adversity, thy strength is small.
11 If thou forbear to deliver them that are drawn unto death, and those that are ready to be slain;
12 If thou sayest, Behold, we knew it not; doth not he that pondereth the heart consider it? and he that keepeth thy soul, doth not he know it? and shall not he render to every man according to his works?
Romans 13
13 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
2 Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation.
3 For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same:
4 For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil.
5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake.
1 Peter 2
13 Submit yourselves to every ordinance of man for the Lord's sake: whether it be to the king, as supreme;
14 Or unto governors, as unto them that are sent by him for the punishment of evildoers, and for the praise of them that do well.
15 For so is the will of God, that with well doing ye may put to silence the ignorance of foolish men:
16 As free, and not using your liberty for a cloke of maliciousness, but as the servants of God.
17 Honour all men. Love the brotherhood. Fear God. Honour the king.
