When the end comes, we will be consumed, and our ash spread upon the earth. Winds will blow our remains across the surface, and settle with the dust. We have no control over this, it is inevitable. So, if death is inevitable, then what?
Some people face the truth with a desire to be kind, since we all face a struggle. Some are deeply selfish, treating others without care, because they don't perceive that they will ever atone. Some people are kind because they live out the system of Karma, the universal principle of cause and effect. Our actions, both good and bad, return to us in the future, helping us to learn from life’s lessons and become better people. I trust in the system of Mercy and Grace. I am not suggested that other people do live wrongly if they pursue Karma. But I haven't seen it work. I am saying that in my understanding, the only perfect life was Christ's, and he was executed by Rome. By this killing he voluntarily took upon himself the sins of others, and God granted humans mercy, and grace, and invited them to enter into communion by repenting, and asking forgiveness.
I am not suggesting anyone stop believing anything they believe. Perhaps your belief system works. But I trust in a system that I have experienced in it working.
