The Israelites were whiners. God rescued them miraculously from Egypt, parted the Red Sea, even, and a little while later this is what they said in Exodus Chapter 16 (quotes from the Message translation)
Why didn’t let us die in comfort in Egypt where we had lamb stew and all the bread we could eat?
Moses talked to God on behalf of the people and He came back to tell them,
God has listened to your complaints against him. You haven’t been complaining against us, you know, but against .”
If that were true of the Israelites then is that true of us as well? When we complain to others, does God view that as complaints against Him?
