How do we know we are to deal with sin in a biblical way?

Dealing with sin biblically involves understanding that human attempts to attain righteousness are futile and that true change comes through God-given faith and repentance. As stated in Romans 8:1, there is no condemnation for those in Christ Jesus, indicating that our struggle with sin should be viewed through the lens of faith in Christ's finished work. This faith entails a recognition that our efforts cannot conquer sin; it must be the work of the Holy Spirit within us. The scripture calls us to turn away from sin, not merely out of obligation, but through the transformative grace provided by the Holy Spirit, who empowers us to seek righteousness through Christ alone.
