The story of Cain and Abel reveals the fundamental difference between approaching God through works versus faith. While Cain brought an offering based on his own efforts, Abel offered a blood sacrifice, demonstrating faith in God's provision for atonement. This ancient account illustrates that God accepts us not based on our performance but through faith in His grace. The New Testament confirms that Abel's offering was more acceptable because it came from faith. This biblical narrative teaches us that justification comes through trusting in God's provision (ultimately fulfilled in Christ) rather than attempting to earn favor through our own merit.
