What does the Bible say about dealing with sin?

According to Romans 8:13, believers are admonished to mortify the deeds of the body through the Spirit. This means actively putting to death the sinful desires and actions that arise from our fallen nature. It highlights the necessity of relying on the Holy Spirit for strength and guidance to live a life that honors God, especially as we grapple with the reality of sin still within us, despite our salvation. It's essential to recognize that walking in the Spirit leads to life and peace, while living according to the flesh ultimately results in death.
