How do we know Christ saves His people?

The certainty of Christ saving His people is anchored in the scriptural promises about His work of redemption, regeneration, and resurrection. In Matthew 1:21, it declares that Jesus shall save His people from their sins. This assertion confirms that salvation is not a mere possibility but a fulfilled promise. Through His sacrificial death and resurrection, He redeems them from the penalty and power of sin as highlighted in texts like 2 Corinthians 5:21. Christ's resurrection serves as God's acceptance of His work, assuring believers that they will also be raised to eternal life, which brings immense comfort and hope.
