We can know all sorts of stuff. When we don't know something, we can quickly come to know what we want to know by simply asking Google, Alexa, or Siri. Many things we know aren't really all that important to know. But there are some things that we absolutely need to know because if we don't know them, the consequences are devastating. In the second half of Daniel 5, we will learn that we need to know that the Most High God rules the kingdom of mankind.
