How do we know we can have peace in death?

Peace in death comes from the assurance that through faith in Christ, we are justified and no longer under condemnation. Romans 8:1 assures us that there is now no condemnation for those who are in Christ Jesus. This means that our relationship with God is secure, and we can face death with confidence, knowing that we are accepted in the beloved. As seen in the life of Peter, who was awaiting execution, he was able to sleep peacefully because he knew his ultimate safety was in Christ and that his death would result in glory (Acts 12:6). This peace comes from the knowledge of our salvation and the hope of eternal life.
