How do we know Noah's obedience was a result of his faith?

Noah's obedience was a direct outcome of his faith in God. As Spurgeon notes, faith was the first principle in Noah's life that motivated his actions. For instance, Hebrews 11:7 states that Noah 'prepared an ark to the saving of his house,' indicating that his obedience was grounded in his belief in God's warning. This demonstrates that true faith leads to action. Noah did not merely believe God but also acted upon that belief, showcasing obedience as a fruit of his faith. His thorough and exact adherence to God's commands reflects a living faith that manifests in diligent and faithful responses.
