Mosiah 3:16

and even if it were possible that little children could sin, they could not be saved; but I say unto you, they are blessed: for behold, as in Adam, or by nature they fall, even so the blood of Christ atoneth for their sins.

Even if little children could sin, they could not be saved without Christ. But I tell you, they are blessed. Just as all people fall because of Adam, Christ’s blood pays for their sins too.

“Even if little children could sin, they wouldn’t need saving—but I tell you, they’re already blessed. Just as all people fall because of Adam’s nature, Christ’s blood covers their sins.”
