Final answer:
Sir Wilfred Grenfell's selfless act of risking his own life to save a boy mirrors the sentiment of John 15:13 about the greatest form of love being the sacrifice of one's life for friends.
Step-by-step explanation:
Sir Wilfred Grenfell's ordeal while attempting to save a boy's life can be likened to the Scripture passage from John 15:13, which states, "Greater love hath no man than this, that a man lay down his life for his friends." Grenfell's selfless and dangerous journey across the ice pan reflects the ultimate sacrifice and commitment to others, as suggested in the biblical verse. His actions demonstrate a profound altruism and courage that align with the Christian ethos of sacrifice for the good of others, as epitomized by Jesus in the New Testament.
