As one who is born again, you no longer have a problem with sin. This is because the nature of sin has been replaced with the nature of righteousness. Some Christians still struggle with sin because they lack sufficient information from the Word of God about who they are in Christ. The Christian is dead to sin, you need to realize what that means; it means sin, shall not have dominion over you; the power of sin over you is completely destroyed.
Some are in places where all they hear about is sin, so sin becomes the focus because they’ve been taught that all have sinned and come short of the glory of God. That’s not the Gospel. It’s better to light a candle than to curse darkness. Therefore, it’s no use talking or complaining about darkness when you can simply turn the light on. God sent us to preach the Gospel, not sin, and the Gospel is good news. The Gospel to the sinner is that by virtue of the death, burial and resurrection of Jesus Christ, he’s been made righteous.
Jesus was made sin for us, who knew no sin, that we might be made the righteousness of God in Him (2 Corinthians 5:21). Therefore rather than preach sin, preach its cure – righteousness. Jesus Christ has made us free from sin and sin consciousness. Christians who still have problems with sin and sin-consciousness are those who are dominated by their senses: “Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin” (Romans 6:6).
Sin has no power over the new creation and should not be the focus. You can live righteously; it begins with being conscious that you’re the righteous and not a sinner, and then talking and living that way. Righteousness is the cure for sin.
