Living a moral life

Living the Christian life is not a matter of following a specific list of rules. Living the Christian life is not taking the specific path that all Christians must take. Living the Christian life is about making moral choices. It is an individual path. All paths follow the cross and biblical teaching, but my path will not look exactly like yours. Within our path we should develop individual convictions and follow those convictions. No one can make those choices and develop those convictions for anyone else. We will all stand before God based on what we as an individual have done. We all need to make these choices for ourselves.
There are, however, several spheres of influence at our disposal for determining right from wrong. These can help us develop our Biblical convictions. The wise man will take advantage of these influences. The foolish man builds his life upon the sand of his arrogant conceits.
The innermost sphere is that of Biblical authority. Anything that violates clear Biblical teaching is clearly wrong. This is were all morality, all convictions must start.
The next sphere is that of authority. For the child, it is parental authority. Whether or not a child feels the rule is justified, and most often they will not, it is their duty to obey their parents. When a child leaves home, he still is responsible to honor his parents, but their convictions are no longer his convictions. He should seek advice from his parents, but his parents no longer have authority over him. For the grown person, the authority is their political authority. Once again, it is not a matter of our agreement with the laws. There are many laws we do not like. Our appreciation of a law is not the prerequisite for our obedience to the law. We must do what our authority tells us to do.
Please note that these spheres are concentric spheres. We should always look to the innermost sphere first. If an outer sphere conflicts with an inner sphere, we should follow in the inner one. We do what God commands no matter what our parents or the government says. If what government requires is not in conflict with what the Bible says, then we follow the law.
The third sphere is that of expediency. We should do only those things that will benefit us spiritually. Some things may not be wrong in the Biblical sense, but they may not be beneficial to us. I cannot find a clear command in Scripture for avoiding wine in all situations. In most situations, though, it is probably not beneficial to our Christian walk to engage in "social drinking."
The absolute last and widest sphere is that of personal preference. When we have gone beyond every other sphere, we look to that which suits our tastes. We may not find any objection to a type of music in any of the other spheres, but we may find it objectionable to our taste. This sphere is not solely about right and wrong. Just because I don't like something doesn't mean it is wrong. It may just mean it is wrong for me. The other spheres are very dogmatic. We can be sure that is wrong to violate Scripture, to dishonor your parents, and to break the law of the land. My tastes, however, are not divinely inspired. If I have no basis in the other spheres, I shouldn't be condemning someone for their tastes.
