What does it mean when it says "spell is not prepared"

Press TAB, then select 'spellbook' at the top of the screen. From here you will see different symbols, one of which will be a little book. Below it will be the spells you have, just click the ones you want and they'll be added next to the book icon.

Depending on what kind of caster you are, you 'know' more spells than you can have "prepared" at once. Clerics are one such caster.

It means you have to select a smaller subset of your spells as ones you actually are able to cast. In tabletop, you can only change these out when long resting, but BG3 lets you do it any time you want (which kind of makes the fact they even bothered to have the mechanic in place kind of stupid).

@Vox already explained how to get to the interface to select which spells you have prepared.

Wizards, druids, paladins are 3 other casters that also work this way. Warlocks and Sorcerers have a smaller list of available spells, but they don't have to prepare any and can always pick from their overall list.
