How do we know that salvation comes from our sins?

In modern evangelicalism, salvation is often viewed merely as a deliverance from hell, yet Scripture presents it as deliverance from sin itself. Matthew 1:21 states that Jesus came to save His people from their sins, highlighting that the core of salvation lies in the eradication of sin's power over believers. By becoming new creations in Christ (2 Corinthians 5:17), Christians experience a profound transformation that frees them from the bondage of sin. This implies a change not only in status before God but also in the very nature of the believer's life and conduct.
