The potential effect of the “Power of the Holy Spirit” on North American natives

In the Tablets of the Divine Plan, the Master pays the utmost attention to this most important matter. He states that if the Power of the Holy Spirit today properly enters into the minds and hearts of the natives of the great American continents that they will become great standard bearers of the Faith, similar to the Nomads (Arabians) who become the most cultured and enlightened people under the Muhammadan civilization.
