In my view.. we have a purpose in this life to acquire virtues and to draw near to God...to love and worship Him... We should leave this world a better place if at all possible and strive to abolish prejudices and work for peace. To me the next world is a spiritual world and with God's mercy we can continue to progress... We can also pray for those still close to us in this world.
There is a sense in which salvation can be both social in this world as well as personal for the individual in a spiritual sense.
