1 John 5:16-17
The concept in these two verses provides a foundation for showing that the Bible clearly categorizes sin in a number of different ways.
First, we must define a few terms. Psalm 119:172 says, "All Your commandments are righteousness." What does the word righteousness mean? It is an Old English word that we still use today, especially in religion. It is slowly being replaced by the word rectitude. Righteousness is a combination of two words, right, meaning "correct," and wise, although it is not spelled anything like our modern word wise. Wisdom is "right application," that is, "right doing." Righteousness, then is "right doing." "All Your commandments are right doing." All unrighteousness—all wrongdoing—is sin.
I John 3:4 reads, "Sin is the transgression of the law." We need to define transgression. Transgress means "to go beyond the limit," "to violate," giving us a broad foundation for understanding this. Sin, then, can be defined as "going beyond the limit of what the law allows." Righteousness is applying the law's letter and/or its intent!
Quite a number of words—Hebrew and Greek—are translated into this single English word sin. A general element that is present in all sin, regardless of which word is used, is failure. Sin equals failure. It is failure to apply or to live up to the standard of what is right. This is why John says that all wrongdoing is failure, but some failure is much more serious than others.
