How do we know that Christ is our security?

The sermon highlights that Christ serves as our security because of God's unchanging purpose and the redemptive purchase made by Jesus through His blood. Isaiah 26:1 affirms that our salvation is appointed by God, emphasizing that it comes from His grace and love towards His elect. None can perish who are secured in God’s sovereign plan. This assurance is further supported by various Scripture references that affirm God's commitment to the salvation of His people, demonstrating that through Christ, we have unshakeable security.
