Sin. It's both a noun and a verb: "It is a sin to..." and "I sinned when..."
To raise the issue of overcoming sin requires we define what a sin is, else how can we be sure we are dealing with sin? And what about actions people claim God commanded that are out and out vile? Are the murders and rapes committed by those who claim no God any different from the lies and manipulations of those who hold God is the reason they act?
Whose definition of sin shall we use?
How do we dertermine culpability?
What action do we take against perpetrators?
for all have sinned and fall short of the glory of God,
No temptation has overtaken you but such as is common to man; and God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will provide the way of escape also, so that you will be able to endure it.
1 Corinthians 10:13
When I began to wrap my heart around the above words as absolute Truth, the groundwork was laid to release me from drives within me that I identified as my homosexuality. I was able to finally realize there was nothing special about my behavior nor that made me worse than anyone else. More importantly, I was able--just able--to believe I was not significantly different.
So what is sin?
In the big picture, literally from the dawn of time until now, sin is what ails the world.
All the wrongs anyone cares to mention and all the ones we don't want to mention or face,
every act of discord between two,
every incidence of familial strife,
all exploitive acts of avarice,
the violence of the one or the gang,
each collective societal rape and plunder by a people group of the nearest other group
and the all-out wars of nations allied against nations,
every last insult,
and each expletive thought against God,
all are rooted in humanity's ingrained, natural inclination to be selfish.
