Why is the death of Jesus important?

In John 12:23, Jesus mentions that 'the hour has come' for Him to be glorified, which directly refers to His impending death and resurrection. His death was not a random event; it was the preordained plan of God meant to bring forth much fruit—namely, the salvation of those chosen to believe. Moreover, His death represents the fulfillment of God's promises and serves as the basis for our justification before God. Jesus, like a corn of wheat, had to fall and die to produce a bountiful harvest of believers.
