Definition: Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.

Explanation: Okay, let’s break down this important verse from 1 John 3:15. It’s a really powerful message about love and how we treat others. Here's what it means in simpler terms: The Basic Idea: This verse essentially says that hatefulness towards your brother is a sign of being a murderer. It’s a very strong warning! Let's unpack it piece by piece: “Whosoever hateth his brother…” – This means someone who actively dislikes, judges, or harms another person. “Hateth” implies a deep, painful dislike. “…is a murderer:” – This is the core of the message. It’s not just any dislike; it's a hatred that goes to the point of causing harm. Murdering someone is considered a grave sin and is irreversible. “and ye know that no murderer hath eternal life abiding in him.” – This is where it gets really important. "Eternal life" refers to a life filled with peace, happiness, and connection with God. But this verse says that if someone has hatred toward their brother, they cannot have an eternal life. It’s like a poison that destroys the soul. In simpler terms: If you constantly criticize, belittle, or harm others, it's a sign of a deep unhappiness and a lack of love for God. That negativity is actively damaging your own soul and preventing you from finding true peace. Why is this important? This verse highlights the importance of kindness, compassion, and forgiveness. It’s a call to be a loving and supportive person, recognizing that our actions affect others. It emphasizes that genuine love for God leads to loving one's neighbor – including your brothers and sisters. Does it mean you have to forgive someone who hurts you? No! This verse doesn’t say you must forgive someone who harms you. It’s a warning about how you treat others. It's about choosing love, even when it's difficult.
