In this life, we have the free will to choose good or evil. The crossing over to the other side can be instant. In the next life, we either end up with or without God and the chasm between two worlds is unbridgeable for all eternity ~ think about it! By not choosing God in this life, you might say that we burn our bridges forever. Seen this way, it's clear that how we live this life is critically important to how we shall live our next life.
