A marine biologist was swimming near the Cook Islands in the South Pacific when a 50,000-pound humpback whale suddenly appeared and tucked her under its fin. The woman thought her life was over. But after swimming slowly in circles, the whale let her go. It’s then that the biologist saw a tiger shark leaving the area. The woman believes the whale had been protecting her—keeping her from danger.

In a world of danger, we’re called to watch out for others. But you might ask yourself, Should I really be expected to be responsible for someone else? Or in Cain’s words: “Am I my brother’s keeper?” (Genesis 4:9). The rest of the Old Testament resounds with the thunderous response: Yes! Just as Adam was to care for the garden, so Cain was to care for Abel. Israel was to keep watch over the vulnerable and care for the needy. Yet they did the opposite—exploiting the people, oppressing the poor, and abdicating the calling to love their neighbors as themselves (Isaiah 3:14–15).

Yet, in the Cain and Abel story, God continued to watch over Cain, even after he was sent away (Genesis 4:15–16). God did for Cain what Cain should have done for Abel. It’s a beautiful foreshadowing of what God in Jesus would come to do for us. Jesus keeps us in His care, and He empowers us to go and do likewise for others.
