This pertains to the definition and not the stated purpose, the problem:What is the dictionary definition of sin? "A transgression of a religious or moral law, especially when deliberate. (Theology) A condition of estrangement from God as a result of breaking his law." This definition is correct for other (non-Christian) religions; however, Christianity and Judaism have their own, very different definition. The word "sin," as a matter of fact, doesn't occur in the original (Old or New) Testaments. The word used in the New Testament is amartais, and it simply means, “to miss God's best.”
For those who are not familiar with scripture, the New Testament was written in Greek. The writers chose to write in this language for a reason. At that time it was the language most commonly spoken by men of all nations. Just like English is spoken today the world over by air traffic controllers. If the world had a universal language, this would've been it.
The translator, seeking an English equivalent for amartais found none. There wasn't a word that even came close to the Bible's definition. The search began for a word that would explain the concept of amartais.
Fortunately, God provided a word that conveyed the concept of amartais. The translator chose the word sin. At that time "sin" had no religious connotation. It was taken from the sport of archery. It was a term that meant an arrow had missed the bull's eye. As a concept, it was uniquely close to amartais. In both cases, something was missed. In the case of archery, it was the black circle at the center of the target. In the case of amartais, it was missing God's best.
Everyone, even peasants, participated in archery. During a time when there was no baseball, football, rugby or soccer, the sport of archery dominated as a sport of skill. It was also used in hunting and war. In hunting, the bow was definitely the tool to use. Therefore, no other word was better known to more people. But even more important, it had the unique ability to convey the correct meaning of the word amartais.
Let’s look at amartais a little more closely now. Why was it necessary to define amartais so precisely? Well, in pagan religions, there were laws and men broke those laws. Breaking man's law is called committing a crime. Breaking religious law is similar to breaking man’s law. Man's punishment varies, but pagan religions said that the punishment for breaking their religious law was being sent to a relatively bad place, such as Hell.
A clear distinction between the Bible's definition and the definition of pagan religions is very important because God wants the world to understand that the Christian God is different from pagan gods. If men don't understand the importance of defining amartais, then they can't understand the sacrifice of the cross or follow in Christ's footsteps. So, you can see why great care was taken in the choice of an English equivalent for amartais.
For years, pagan religions had advanced the idea that man had control of himself and, through a bit of complicated legal logic, they also thought that man could control his entrance to Heaven! Let me explain. After years of pagan teaching, the popular belief was (and is) that Heaven and Hell are, respectively, the reward and punishment for the choices made in life. Some uninformed Christians think this pagan idea comes from the Bible.
At the heart of this pagan belief system was the idea that man could choose to be either good or bad. If you accept these concepts, then the final conclusion will be that with the proper currency (your good choices) entry to Heaven can be purchased. Yes, spoken simply, being good (following a pagan religion's laws) will buy you a ticket to Heaven.
This opposes Christian teaching. The Bible says that sin controls us and that we are all (without God's help) headed for Hell. Furthermore, the Bible clearly states that man cannot earn Heaven. In Ephesians 2:5-9 it says, ". . .by grace are ye saved. . . in heavenly places. . .by grace are ye saved through faith and that not of yourselves: it is the gift of God: not of works, lest any man should boast." In plain English that means that you can't buy Heaven. Let me say it again, “You can’t buy your way into Heaven by being good.
Heaven is a gift. We recognize this as a Christian concept. We have been taught this concept by the modern church.
So why are modern Christians unable to define an important word like sin?
A few hundred years after the death of Christ, the church had a problem. It tried to answer the problem created by the Bible’s definition for sin, amartais, but couldn't.
