Christ's covenant is confirmed through His death, which secures the promises of salvation for believers.
The authenticity of Christ's covenant is established by His sacrificial death, which serves as the testator's act that puts the covenant into effect. As highlighted in Hebrews 9, a will only becomes actionable upon the death of the one who made it. In Christ's death, we find the essential means by which God's promises take effect, thereby securing salvation for His people. This covenant reflects everything that believers receive, including adoption, the Holy Spirit, righteousness, and eternal life. Each blessing is anchored in the trustworthiness of Christ, who is faithful to uphold the commitments made to His elect, as reiterated in Romans 8:15-17. Therefore, the certainty of Christ's covenant is grounded in His selfless sacrifice, ensuring that we can approach God with confidence.
