Sin

Sin is often used to mean an action that is prohibited or considered wrong; in some religions (notably some sects of Christianity) sin can refer to a state of mind rather than a specific action. Colloquially, any thought, word, or act considered immoral, shameful, harmful, or alienating might be termed "sinful". The word Sin occurs 448 times in 389 verses in the KJV. In the Spanish language, sin means "without". When an archer misses the bull's eye, it is called a sin. Here is the Strong's version of Sin:
to sin, miss, miss the way, go wrong, incur guilt, forfeit, purify from uncleanness
a) (Qal)
1) to miss
2) to sin, miss the goal or path of right and duty
3) to incur guilt, incur penalty by sin, forfeit
b) (Piel)
1) to bear loss
2) to make a sin-offering
3) to purify from sin
4) to purify from uncleanness
c) (Hiphil)
1) to miss the mark
2) to induce to sin, cause to sin
3) to bring into guilt or condemnation or punishment
d) (Hithpael)
1) to miss oneself, lose oneself, wander from the way
2) to purify oneself from uncleanness
So what are we to do? And how are we to classify what "sin" really is? So my take on sin is this…If we differ from God's plan, then we sinned. Take Adam and Eve. They did not listen to God's plan and ate after being explicitly told not to. So we have all sinned, we have all missed the mark. We have all "wandered from the way" and incurred guilt.
