Mystries of God

To know the Mystries of God, we need to diligently study, seek and ask.

We must also purify ourself from the ways of the world. We must discover our weaknesses and repent of our sins. Promises given in the scriptures are for all men.

God is no respector of persons, he is the same today, yesterday and forever.

Promised Blessing.

And when ye shall receive these things, I would exhort you that ye would ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost

And by the power of the Holy Ghost ye may know the truth of all things.
