I want to believe that Jesus showed that 'death' is not the end of life.
the dead remain alive, most, if not all, reincarnate back to undo the poor deeds of past life or to continue in good service having learned from the past or to continue with the soul's mission. Much goes beyond death, responsbility likewise goes beyond death. 'you reap what you sow' goes beyond death.
why wait until judgement day? it's like being in a kitchen, if all utensils are dirty, why wait until meal-time? you may not have enough time to clean all the utensils, and if you dont who else will? this is the literal meaning of 'you reap what you sow', it's a responsibility issue tagged upon all us. cleaning dirty utensils is similar to cleaning up you acts starting with thoughts, then deeds, its a tedious process.
