For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hinder the truth in unrighteousness; because that which is known of God is manifest in them; for God manifested it unto them. For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse: because that, knowing God, they glorified him not as God, neither gave thanks; but became vain in their reasonings, and their senseless heart was darkened. Professing themselves to be wise, they became fools, and changed the glory of the incorruptible God for the likeness of an image of corruptible man, and of birds, and four-footed beasts, and creeping things. Wherefore God gave them up in the lusts of their hearts unto uncleanness, that their bodies should be dishonored among themselves: for that they exchanged the truth of God for a lie, and worshipped and served the creature rather than the Creator, who is blessed for ever. Amen. For this cause God gave them up unto vile passions: for their women changed the natural use into that which is against nature: and likewise also the men, leaving the natural use of the woman, burned in their lust one toward another, men with men working unseemliness, and receiving in themselves that recompense of their error which was due. And even as they refused to have God in their knowledge, God gave them up unto a reprobate mind, to do those things which are not fitting; being filled with all unrighteousness, wickedness, covetousness, maliciousness; full of envy, murder, strife, deceit, malignity; whisperers, backbiters, hateful to God, insolent, haughty, boastful, inventors of evil things, disobedient to parents, without understanding, covenant-breakers, without natural affection, unmerciful: who, knowing the ordinance of God, that they that practise such things are worthy of death, not only do the same, but also consent with them that practise them.

But I say, Walk by the Spirit, and ye shall not fulfil the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh; for these are contrary the one to the other; that ye may not do the things that ye would. But if ye are led by the Spirit, ye are not under the law. Now the works of the flesh are manifest, which are these: fornication, uncleanness, lasciviousness, idolatry, sorcery, enmities, strife, jealousies, wraths, factions, divisions, parties, envyings, drunkenness, revellings, and such like; of which I forewarn you, even as I did forewarn you, that they who practise such things shall not inherit the kingdom of God.
Bible Gateway passage: Galatians 5:16, Galatians 5:17, Galatians 5:18, Galatians 5:19, Galatians 5:20, Galatians 5:21 - American Standard Version
But fornication, and all uncleanness, or covetousness, let it not even be named among you, as becometh saints; nor filthiness, nor foolish talking, or jesting, which are not befitting: but rather giving of thanks. For this ye know of a surety, that no fornicator, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and God. Let no man deceive you with empty words: for because of these things cometh the wrath of God upon the sons of disobedience. Be not ye therefore partakers with them; for ye were once darkness, but are now light in the Lord: walk as children of light (for the fruit of the light is in all goodness and righteousness and truth), proving what is well-pleasing unto the Lord; and have no fellowship with the unfruitful works of darkness, but rather even reprove them; for the things which are done by them in secret it is a shame even to speak of. But all things when they are reproved are made manifest by the light: for everything that is made manifest is light. Wherefore he saith, Awake, thou that sleepest, and arise from the dead, and Christ shall shine upon thee. Look therefore carefully how ye walk, not as unwise, but as wise; redeeming the time, because the days are evil. Wherefore be ye not foolish, but understand what the will of the Lord is. And be not drunken with wine, wherein is riot, but be filled with the Spirit; speaking one to another in psalms and hymns and spiritual songs, singing and making melody with your heart to the Lord; giving thanks always for all things in the name of our Lord Jesus Christ to God, even the Father;
But fornication, and all uncleanness, or covetousness, let it not even be named among you, as becometh saints;

So if Christian imperatives need to be the laws of the land, then these imperatives need to be as well. If we are going to desire that our state follow the scriptures, the we should desire they use all of them in their governance. I really don't find anything in scripture that says we only have follow the things we want to. The rest is optional. No, thats not there.
