What does 'consummation' mean in the context of salvation?

In theological terms, 'consummation' represents the finalizing of God's redemptive plan as embodied by Jesus Christ. This concept expands from His utterance 'It is finished' and denotes that His sacrificial act not only atoned for sin but also inaugurated a new covenant. The consummation includes the fulfillment of Old Testament prophecies and the complete satisfaction of God's justice. For Christians, this means that their redemption is secured and that they await the final consummation of all things when Christ returns to restore and complete His creation.
