8 Now Cain talked with Abel his brother; and it came to pass, when they were in the field, that Cain rose up against Abel his brother and killed him. 9 Then the Lord said to Cain, “Where is Abel your brother?” He said, “I do not know. Am I my brother’s keeper?” (Genesis 4:8–9, NKJV)
Cain tried to evade the force of God’s question by lying to God and implying he was not his brother’s guardian. Cain hated his brother and murdered him “because his works were evil and his brother’s righteous” (1 Jno. 3:11-15). Hatred destroys life (“whoever hates his brother is a murderer”, 1 Jno. 3:15). Love protects life (“By this we know love, because He laid down His life for us. And we ought to lay down our lives for the brethren”, 1 Jno. 3:16). Remember that you are your brother’s keeper. Not only are we to love and protect our fleshly brothers and sisters, but even more so, our brethren in Christ. Guard and protect your brethren, do not hate them. Out of love be a protector of life, not a murderer, because “you know that no murderer has eternal life abiding in him” (1 Jno. 3:15).
