How do we know that Christ's resurrection guarantees our salvation?

Romans 4:25 states that Christ was 'raised for our justification.' His resurrection serves as a divine affirmation that His atoning sacrifice for sin was accepted by God. This assurance ensures that all for whom He died will indeed have their sins paid in full and will be raised to eternal life. The resurrection of Christ not only signifies His victory over death but also the hope of believers that they too will be resurrected. As Paul expresses in Philippians 3, the knowledge of this promise and power of resurrection is central to the believer's faith, offering both present hope and future assurance.
