alright, i have 2, like always.
first, the bible.
well, i don't have this exact bible, but anyways! i don't think anyone would be able to live without the word of God. its the instructions to living your life. and what God wants us to know. i wouldn't be able to live without this.
last, LOVE. i think this is pretty self explanitory, but just love in general, friends, family, and even true love.
