She uses D.Pathos. She's using an emotional approach to her students. She's not using data or statistics to prove her point. She is also not talking about being morally right.
Eliezer's confidence is a result of his examinations in Jewish mystery, which show him that God is wherever on the planet, that nothing exists without God, that in actuality everything in the physical world is a "spread," or reflection, of the awesome world. At the end of the day, Eliezer has grown up trusting that everything on Earth mirrors God's sacredness and power. His confidence is grounded in the possibility that God is all around, constantly, that his heavenliness touches each part of his day by day life. Since God is great, his investigations show him, and God is wherever on the planet, the world should accordingly be great.
