The quote from "Redeeming Love" highlights a character's internal struggle with trust and faith. He grapples with the idea that if he believes in the Lord's protection and care, he should also trust that the same would extend to someone else, particularly someone who lacks belief. This reflects his conflict between his own faith and the doubts stemming from witnessing another's skepticism.
This situation emphasizes a common theme in literature: the challenge of sharing one's faith with others. The character's reluctance to fully trust in the Lord's guidance for her reveals the complexities of relationships where differing beliefs exist. Ultimately, it raises questions about the nature of faith and the extent to which it can be shared or imposed on others.
