What term describes the redemption of the believer's body at Christ's return?

The term that describes the redemption of the believer's body at Christ's return is glorification. This doctrine refers to the transformative process that occurs when believers are united with Christ and their mortal bodies are changed into immortal ones. In Christian theology, glorification is the final step in the salvation process, following justification and sanctification.

Justification refers to the believer being declared righteous before God at the moment of faith in Christ, while sanctification involves the process of becoming more like Christ throughout life. Exaltation typically refers to Christ's elevation to a position of highest honor, rather than the transformation of believers. Thus, glorification specifically captures the idea of the final transformation and fulfillment of the believer's hope in the resurrection at Christ’s return.
