What the Bible says about God as Faithful
(From Forerunner Commentary)
This description of God is exactly the opposite of that of America's national character. Our God is a God of truth, meaning He is unswervingly faithful. He is the Rock, implying One who is impervious to change. He is our Foundation, indicating One who provides firm footing in a way of life. He is our Fountain, the Source of a refreshing, productive way of life that He intends His people to use.
