All water, food reserves are going to end up and what then ? We better train the trust, the faith in God's Mercy. He can supply us in everything we need if we really love Him, love His Son, Jesus. In Sodom and Gomor God looked for 10 just, honest people but there weren't. I believe, now God looks for merciful people in each countries. If finds more than 10 a country still exists. What if the number falls under 10 ?
