Why talk about SIN?

Some of the best attended “churches” in America are led by “preachers” who either avoid or minimize the topic of Sin. 
So, if there are many people who decide not to address the subject, and if there are many more who do not want to hear about it, then why in the world would anyone bring it up? Well, that is a good question…
First, it inevitably comes up. Even if someone doesn’t use the word “sin,” they are most certainly going to use some vocabulary to describe the difference between what is “good” and what is “bad.”  Consider this: Is it good to lie? Is it moral to murder? Is it right to oppress others? Each of these questions requires an answer that will necessarily involve the concept of sin, because Sin is any lack of conformity to or disobedience of God’s commands (God’s moral law).
If it is not good to murder, then why is it not good? Such an absolute judgment of morality forces an appeal to some transcendent truth or law. Therefore, one may appropriately argue, murder is not good (i.e. it is wrong) because God commands the protection and preservation of life. To disobey such a command is wrong, not good, and sinful. One may leave off the “sinful” part, but the concept has necessarily been at least introduced.
Second, Jesus talked about sin… a lot. Even a skim across the surface of the four Gospels (Matthew, Mark, Luke, and John) will cause the reader to notice that Jesus was very interested in the subject of sin. Jesus called people out for being sinners (Jn. 8:21); Jesus talked about the negatively captivating effects of sin (Jn. 8:34); and Jesus talked about the need to be free from sin (Jn. 8:36). This is just a short look at a single passage, but the Gospels are full of this kind of talk from Jesus. One might argue that the primary reason God became a man in Jesus Christ was to address the matter of sin (Matt. 26:28).
If the Bible is true about human nature, then all people everywhere are in dire need of something or someone to address their problem with sin. Any honest person must acknowledge that sin is a topic that cannot be avoided by anyone. And, if we are to follow Christ, then we must be willing to submit to His words and stress those things He has already highlighted.
“All have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a satisfying offering by his blood, to be received by faith… so that God might be just and the justifier of the one who has faith in Jesus.” (Romans 3:23–26)
May we come to grips with the nastiness of our sin so that we may appropriately marvel at the grace of Christ.
