Why can't God save all mankind, regardless of believe or disbelieve? God is love, righteousness and just. The crucifixion of Jesus is his greatest plan to bring back the salvation to mankind. However there is only one condition to receive the salvation, that is; we have to believe in Jesus by our own free will. Why so? That's the question. I believe this condition is a heavenly justice which God has to uphold. It is so important and cannot be overruled by God himself. To me, 'believe' means more than its literal meaning. For example, it's hard for an evil-doing person to believe in Jesus, because 'believe' is like the door to goodness, and out of his evil conscience, he chooses not to open it. May be, 'believe' is a test of our conscience and a judgment of our soul, although it might has a hidden meaning and a purpose in the heavenly dimension. Once we have accepted Jesus as our savior, the Holy Spirit lives inside us so that our bonds with God can be restored. As Christians, we experience a change in life. We have the conscience and we feel guilty and ashamed of our sins. God continually teaches us and reminds us to repent from our sins. Although our fresh is week, but we love God truly, and with the help of the Holy Spirit, it is possible to fight the evil inside us. Believe with your heart, and gradually you will have a good soul, but not perfect….. as only God alone is perfect. end...
