Alma 30:15

How do ye know of their surety? Behold, ye cannot know of things which ye do not see; therefore ye cannot know that there shall be a Christ.

How do you know they’re true? You can’t know about things you can’t see. So you can’t know there will be a Christ.

'How do you know they’re true? You can’t know things you haven’t seen. So you can’t know there will be a Christ.'
