This is an interesting question because it assumes there are items that are indispensable. But, to be honest, everything is indispensable except for love: God’s love, my family’s love, even my dog’s love. My cellphone is an incredible convenience, but if I didn’t have it I’d be OK if I still had love. My car is wonderful, but the bus would work just fine as long as I still had love. And my laptops (both personal and work) help me get my work done. But I’d figure out how to do it with pen and paper as long as I had love. Saying that reminds me of someone much smarter than myself who basically had the same idea a long time ago:
“If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing. If I give away all I have, and if I deliver up my body to be burned,[a] but have not love, I gain nothing.” (1 Corinthians 13:1-3)
When it comes down to it, love is the only thing I can’t live without it. And if you’re honest with yourself, it’s also the only thing you – or anyone – can’t without.
