If the Abrahamic God is perfect and possesses unconditional love, why are there pre-requisites to salvation?

You aren't using words correctly, but are stipulating definitions, that are wrong. YAHOSHUA offers salvation. It is like a marriage contract. Take His name, follow His rules, you become His 'bride' and He saves you. If you choose death, He has promised not to interfere. How could He be more generous????
