A tiny needle sinks into the water. Rain falls — it cannot float in the air. These are natural laws. A person who kills a tiny ant falls into hell. Thus, a person who kills a human being falls into hell.
However, a huge rock can float on water if it is placed on a ship. A raging fire can be extinguished by the power of water. Without repentance, even a small sin can make a man fall into hell. On the other hand, with sincere repentance, even great sins can be erased.
