A.W. Pink expounds on the Sixth Commandment, 'Thou shalt not kill,' emphasizing that it not only forbids murder but also the underlying emotions such as anger and hatred that can lead to it. He illustrates how the commandment serves to protect the sanctity of life and the well-being of individuals, warning against the dangers of envy and rash anger. Pink highlights that lawful actions, such as capital punishment and just wars, do not violate this commandment, while also addressing the grave sin of suicide as self-murder. He concludes with practical advice on managing anger and cultivating a humble spirit to prevent the escalation of harmful emotions. The sermon calls for a deeper understanding of the commandment's implications for personal conduct and community relations.
