The quote "Nothing true can be said about God from a posture of defense" from Marilynne Robinson's book, Gilead, emphasizes the idea that discussions about God should not stem from a position of needing to justify or protect one's beliefs. When individuals approach the concept of God with a defensive mindset, they may close themselves off from deeper understanding and genuine engagement with faith and spirituality.

This perspective encourages openness and humility in theological conversations. Rather than defending preconceived notions or dogmas, one should seek to explore and express thoughts about God with authenticity and vulnerability, allowing for a richer and more honest dialogue about faith and existence.
