Moroni 10:7

And ye may know that he is, by the power of the Holy Ghost; wherefore I would exhort you, that ye deny not the power of God: for he worketh by power, according to the faith of the children of men, the same to-day, and to-morrow, and forever.

You can know that he is real by the power of the Holy Spirit. So I want you not to reject God’s power. He works by power, based on how much people have faith. He does this today, tomorrow, and forever.

You can know he’s real by the power of the Holy Spirit. So don’t deny the power of God. He works through power, according to people’s faith—the same today, tomorrow, and forever.
