The Scripture today does not merely focus our attention on to Good Friday, but to the Second Coming of Christ.
Christ is telling us that His hour of glory is coming, which is the winning of salvation for mankind through the Passion, Death, and Resurrection.
But, the prophecy which Christ is giving about His death also points to the final glorification of His coming at the end of the world. Christ's Second Coming will be the great moment of His glorification, as the entire world, all the living and the dead will look on Him whose hands, feet, and side hold the wounds of His victory.
This final glorification encompasses the entire Gospel message. All will be judged by this Gospel.
The judgment which happens on Calvary will be finalized on that Last Day.
Through suffering, Christ earns His Kingdom, as God the Father willed.
Christ is the grain and we are the harvest. Do not waste His suffering in your life.
