If we’re going to take a close look at something that we’re all guilty of doing, it may be advisable to dig in with a little research. We begin by going to our Webster’s dictionary for the definition of sin:
1 a: a transgression of religious law: an offense against God b: a serious offense: a violation of propriety c: a serious shortcoming:
2: violation of religious law: disregard of God's Will
A disregard of Gods Will says it all. Next we explore God’s word to broaden our knowledge of sin. 1 John 3:4-5 KJV picks up where our Webster’s left off:
 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
 And ye know that he was manifested to take away our sins; and in him is no sin.
God has a set of rules for us to follow and simply put, going against them is sin. Notice that Christ, the only one without sin, will take away our sin but we are required to ask!
You may ask: where did such a pesky thing as sin come from, anyways? Allow Paul to introduce Satan, the one we know as Death, in 1 Corinthians 15:56 KJV:
The sting of death is sin; and the strength of sin is the law[
Yes, Satan is sin and he welcomes and tempts you to join him in his world of sin. It requires strength to follow God’s Law and to resist the Tempter, Satan, who is death. Christ though, through forgiveness, awaits you when you fall short.
We receive confirmation that Satan is the father of sin in 1 John 3:8 KJV:
He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
Observe that God, from the beginning, has allowed Satan to obtain followers; that’s why one of Satan’s names is “Tempter”. God sent His only Begotten Son to defeat Satan; the death of Christ, through forgiveness, will defeat sin which is defeating the works of Satan. We cannot deny this exposure to sin nor can we deny our participation in sin. God clearly makes this point to us in 1 John 1:8 KJV:
If we say that we have no sin, we deceive ourselves, and the truth is not in us.
We recognize that the truth is in us and we recognize that God allows Satan to test us through sin. It is our choice to refuse Satan’s advances and when we fail, the Blood of Christ is available to wash these sins away. God’s Word clarifies this point in John 1:29 KJV:
The next day John seeth Jesus coming
