Daniel, Job, and Noah

Daniel, Job and Noah were described as righteous in Ezekiel 14:13-23. What was the secret to their remaining in right standing with their Lord God, Jehovah. Why did they choose to remain loyal to Yahweh? How did they maintain such strong faith when so many others had turned back on God Almighty? Regardless of their title, position in the community, material possession they gave glory to the Most High God and trusted Him. Persecuted for their beliefs, they remained steadfast. Obedience to their creator, Elohim were top priority for them. They lived in a period when men and women did what was right in their own eyesight not what was well pleasing to El Shaddai. So many others were worshipping idols, what stopped them from bowing their knees to serve the idol gods? Why was it so important to them to be found faithful?
