How does Cain's rejection of God's way reflect human depravity?

Cain's response to God's rejection of his offering showcases the depth of human depravity. Rather than seeking to understand why his offering was not accepted, Cain became angry and despondent, demonstrating a lack of submission to God's authority. This pattern reflects the inherent rebelliousness found in all humanity post-Fall, where individuals seek to approach God through their own means rather than according to His commandments. Cain's actions reveal that human beings, in their unregenerate state, prefer self-will to God's sovereign grace, leading to actions that result in spiritual death. The account serves as a reminder of the necessity for divine intervention to transform hearts and minds to align with God's will.
