Axiomatic

7But when [John the Baptist] saw many Pharisees and Sadducees coming to watch him baptize, he denounced them. “You brood of snakes!” he exclaimed. “Who warned you to flee God’s coming wrath? 8Prove by the way you live that you have repented of your sins and turned to God. 9Don’t just say to each other, ‘We’re safe, for we are descendants of Abraham.’ That means nothing, for I tell you, God can create children of Abraham from these very stones. (Matt 3:7-9 emphasis added)

You say you have faith, for you believe that there is one God. Good for you! Even the demons believe this, and they tremble in terror. (James 2:19)
