What does a unilateral covenant mean?

In biblical terms, a unilateral covenant refers to an agreement where only one party redresses all conditions, unlike bilateral covenants that require mutual obligations. The New Covenant established through Christ's sacrifice is unilateral, meaning that its fulfillment and efficacy depend entirely on the actions of Jesus, who paid the penalty for sin and achieved righteousness on behalf of His people. This concept underscores that believers do not contribute to their salvation through works, but receive it purely by faith in Christ. The assurance of salvation offered in this New Covenant confirms that once a person is in Christ, their standing is secure, as God’s promises are unwavering and rooted in Christ’s finished work.
