How do we know Jesus saves us from sin?

Jesus' role as Savior is profoundly detailed in Scripture, particularly in Matthew 1:21, where the angel tells Joseph that Mary will give birth to a son named Jesus, for He will save His people from their sins. This statement encapsulates the essence of salvation offered through Christ. Our need for salvation arises from our inherent sinfulness, and thus, the salvation provided by Jesus must address this fundamental issue. Through His sacrificial death, Jesus pays the penalty for our sins, ensuring that believers are not held accountable for them. Additionally, the concept of justification comes into play, where believers are declared righteous based on Christ's merits, further validating that Jesus indeed saves us from the consequences of sin.
