As a project that could take weeks of leisure research and taking notes:
Notice and note ALL the times ''belief and believe'' is said in the New Testament.
Note what is promised if you only believe. ONLY believe.
There are secular books written with titles like The Power of Belief, Believe in the Power of Believing,
Biology of Belief, The Belief Principle, Belief is the New Black.
Then, all the books by Christian authors.
AND all the books on a doff twist - the power of - for example : "I'll never get that job." And you never do
Fun project.
