Alma 12:22

Now Alma saith unto him, This is the thing which I was about to explain. Now we see that Adam did fall by partaking of the forbidden fruit, according to the word of God; and thus we see, that by his fall, that all mankind became a lost and a fallen people.

Alma said to him: This is what I was about to explain. We see that Adam did eat the fruit God told him not to eat. This is what God’s word says. Because Adam did this, all people became lost.

Alma answered, “That’s exactly what I was about to explain. Adam did fall by eating the forbidden fruit, just as God said he would. And because of his fall, all humanity became lost and fallen.
