What is the difference between nichiren daishonins Buddhism and Christianity?

Nichiren Daishonin's Buddhism centers on the teachings of the 13th-century Japanese monk Nichiren, emphasizing the chanting of the phrase "Nam-myoho-renge-kyo" as a means to attain enlightenment and achieve personal empowerment. It focuses on the concept of the Lotus Sutra as the ultimate teaching of the Buddha. In contrast, Christianity is based on the life and teachings of Jesus Christ, emphasizing faith in God, salvation through grace, and the significance of The Bible. While both traditions value spiritual transformation, their beliefs, practices, and foundational texts differ significantly.
