Christians - Are we our Brother’s Keepers?

Cain asked this question in response to God's question, "Where is Abel thy brother?" God did not ask Cain where Abel was because He did not know. God knew that Cain had killed his brother. Cain replied, "I know not..." This was a lie, for Cain knew that he had just killed his brother. Cain's question, "Am I my brother's keeper" was intended to deceive. It revealed a cynical and hardened heart.
