How does the grand narrative impact/influence psychology?? Please provide some much needed insight and detail correlation of the two topics. Thank you. (I provided brief summary below of Christiaan grand narrative)

The grand redemptive narrative of the bible describes God as a creator of a perfect world that human compromises through their sin which led God to send his son Jesus to die as payment for our sins, therefore allowing us to be reunited with God in Heaven one day.

Please explain and elaborate on correlation!????
