Indeed. You are preaching to the choir. I believe in progressive revelation, which means that God reveals more truth in every successive age, which is tailored to the needs of the people who are living in the present age.
Progressive revelation is a core teaching in the Bahá'í Faith that suggests that religious truth is revealed by God progressively and cyclically over time through a series of divine Messengers, and that the teachings are tailored to suit the needs of the time and place of their appearance.[1][2] Thus, the Bahá'í teachings recognize the divine origin of several world religions as different stages in the history of one religion, while believing that the revelation of Bahá'u'lláh is the most recent (though not the last—that there will never be a last), and therefore the most relevant to modern society.[1]
It is not that God
changes His mind, it is that God knows what humanity needs at any particular time in history, so God reveals a new message in every age.
“The All-Knowing Physician hath His finger on the pulse of mankind. He perceiveth the disease, and prescribeth, in His unerring wisdom, the remedy. Every age hath its own problem, and every soul its particular aspiration. The remedy the world needeth in its present-day afflictions can never be the same as that which a subsequent age may require. Be anxiously concerned with the needs of the age ye live in, and center your deliberations on its exigencies and requirements."
