"Greater love has no one than this, that one lay down his life for his friends"(John 15:13 ).

Hint: As a christian, whenever you read Jesus's parables, ask yourself this simple question: What's the secular(literal) interpretation of this passage and what might be the "spiritual" interpretation of the same? Surely, the faults of many "christians" is that the only difference between them and secular/non-christian people is just a label and belief in the man Jesus but their reasoning and interpretation of scripture remains the same... So Let's try and reason spiritually.

1, What is love??
2, Who is your friend??
3, What does it mean to "lay down your life"??
