Answer:
The central idea of this passage is the importance of faith.
Explanation:
The passage is about people who faced some difficulties when they moved to another place. They cried and their Lord heard them.
The passage says "Lord" and It's refering to "God" and when It says that "the Lord heard them" It means that God provided them what they needed. That's why at the beginning of the passage says "what could now sustain them but the Spirit of God and His grace? It means that only God could do something for them. So the central idea of this passage is the importance of faith.
