It is not that God elects some for Heaven and some for Hell - unbelief is the only reason people face eternal death. They are all centered around the believer becoming like Christ. What the unsaved need to be concerned with is the conviction of the Holy Spirit of the need of salvation. By their rejection, they doom themselves to Hell. Verses 40 and 44 teach that the true Kingdom of Christ is an eternal kingdom.
Most people live for the present, making no provision for eternity.
The whole grain of Scripture teaches us that things of eternal value are far more important than the temporal items we may possess now. Read the sad O.T. story of Solomon, King David's son and heir to the riches of his throne, to see what value is ultimately placed on a life lived for the present. Jesus taught them the value of self-sacrifice. He taught them of His soon-coming sacrifice for the sins of mankind. It is not how much we gain that counts, but how much we give.
