I think everyone has touched on some element of how to not sin. Just reading through the replies is edifying and encouraging to me!
As someone who is constantly screaming (internally) at pastors, "Yes, I understand what you're saying but HOW? What's the practical application of this in our lives?!" I can relate to what Blaine is actually asking. (If I'm wrong, Blaine, please correct me. Sometimes I can over-analyze posts!)
Dying to self and loving God are definitely the ANSWERS to not sinning. But Blaine is asking HOW do we do that? HOW do we not sin? HOW do we die to self? HOW can we love God? Knowledge alone isn't enough. It must be applied to WORK.
All I can do is give my own method.
There is a period of time that occurs before a sin is committed. A time when the conscience speaks out to advise us that we know better; that what just crossed our mind that our body wants to do/say is wrong, or a lie. It's self-centeredness, pride, the lack of self-control and ego that goads us with, "Just do/say it! You've already done/said something like this a million times before anyway! What's one more sin for God to forgive you for? It's a small one anyway! Just do/say it! You feel better! You'll show that other person they shouldn't mess with you or treat you that way!"
You know those dozen or so thoughts that go through your mind in a twinkling of an eye before you let loose on that sin? THAT'S the time before the sin that I'm talking about.
Whenever I'm tempted to sin, off all things or of all people, Ronald and Nancy Reagan ALWAYS come to mind before I sin. (It really IS remarkable how many thoughts can run through your mind in a twinkling of an eye to a few seconds.)
I ALWAYS hear Ronald Reagan saying, "Well, Nancy says to just say NO!"
There's so much truth and maturity in that. Just say no. Here's an example: I got to work with my friend who has a carpet cleaning van today. We were shampooing the carpet of a vacant apartment that was recently renovated. One of the guys working on the renovations came in. As he passed by me, said he had some work to do in the bathroom. I smelled alcohol on his breath. I wanted to turn to my friend and say, "Looks like someone had a liquid lunch today."
As God is my witness, this was my entire thought process in just a few seconds:
"What? That's so rude! I may like to be funny once in awhile but I'm not a mean person! Still it would be funny and not really hurt anyone and my friend would get a chuckle out of it. Yeah, but at this man's expense, unbeknownst to him? All he did was come in to do a job! Do you know WHY he drinks during the day? Do you know his struggles or what he may be currently going through? Show some compassion."
Then 1 Peter 4:6 came to mind, "And above all things have fervent love for one another, for "love will cover a multitude of sins."
(Thought process continuing...)
"Sins aren't covered by jokes and gossiping. Jesus not only covered all of my sins, He forgave them completely.
I'm going to practice self-control and discipline and NOT say that to my friend. I want Jesus to be proud of me."
So, that's my practical way of dealing with sin: Ronald and Nancy Reagan and the short, but powerful phrase: "Just say NO!" It's possible to just say no. We just don't like going through the self-denial (dying to self part) or loving God more than ourselves. Odd, I know. But it works for me.
There IS a time that passes before we CHOOSE to commit sin. And it IS long enough to reason out and choose holiness. It IS enough time to turn away from that sin. Will we be controlled by self-discipline and the love of God and others? Or are we not filled enough with the Word and spending abiding time with Jesus? Are we instead filled with our own desires and self-centered thinking? "I can't help it" is a self-centered cop-out. Or, in today's humanistic vernacular, "That's just how I'm wired." Or, "Sorry if you don't like it but I'm not changing who I am."
It IS a choice. Just say no and choose Jesus. Choose holiness.
