What does the Bible say about salvation through Christ?

The concept of salvation is central to the biblical message, as illustrated in Matthew 1:21, where it states that Jesus will save His people from their sins. This reflects the foundational belief in the sovereignty of God in salvation, affirming that it is through Christ alone that redemption is achieved. The salvific work of Christ embodies the principle of substitutionary atonement, where He bore our iniquities (Isaiah 53:5) and justifies us before God (Romans 5:1). Therefore, salvation is a gift of grace that cannot be earned through human effort but is received through faith in Jesus Christ.
