Those who love Jesus because they have received forgiveness of their sins through faith in His substitutionary atonement, will love others - not because these "others" are lovable but because Jesus has saved them from God's righteous and necessary wrath against sin.
Furthermore, what or whom one loves in this life is what or whom one will love after passing through the shadow of death. If one has never loved Jesus, and because of Him, loved others, in this life, then one will not suddenly descover such a love after death.
