What do you think the title of this chapter means? (The foolish and the weak) A wrinkle in time chapter 12

The title of the chapter - The Foolish and the Weak - also is an allusion to a passage of the Bible. Once again, in reference to the writings of the apostle Paul, the chapter alludes to the way in which Meg’s own strength and courage are not enough to save her brother. God’s love is stronger than any selfish emotion, and it is this kind of love that Meg must rely on to save her family. In this way, Meg symbolizes the weak and foolish of the world that God uses to defeat evil.
