The deceitfulness of sin

"Do you love me?" Jesus says those words to Simon after being denied being known by him three times. Yet the bible is clear about what we as believers are supposed to do if we love God.
2 John 1:6 NASB
And this is love, that we walk according to His commandments. This is the commandment, just as you have heard from the beginning, that you should walk in it.
John 14:15 NASB
"If you love Me, you will keep My commandments.

Our conscience bears witness as to whether we are in sin or not, and if our conscience is seared or hardened, we are in a trouble. Our hardened hearts will seek life in sin and our condemnation is worse.
Unfortunately in modern "christianity" it is a no go zone. I put it that way because if it is not the Christian walk according to the bible then can one really say they are following Christ?
There are some misconceptions when it comes to sin, and I want to confront it with the truth of the bible.

1) It does not hurt anyone.

Romans 6:23 NASB
For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.

2) No one has any right to confront me.

Matthew 18:15-17 NASB
"If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother. But if he does not listen to you, take one or two more with you, so that by THE MOUTH OF TWO OR THREE WITNESSES EVERY FACT MAY BE CONFIRMED. If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
1 John 5:16-17 NASB
If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this. All unrighteousness is sin, and there is a sin not leading to death.
Proverbs 27:5-6 NASB
Better is open rebuke Than love that is concealed. Faithful are the wounds of a friend, But deceitful are the kisses of an enemy.

3) As long as I don't hear that it's wrong as long as I don't read it in the bible I am good.

Romans 2:14-16 NASB
For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.

As Christians we have to wage battle against sin. We have to grown in holiness. Day by day I want to be conformed to the image of Christ.
