What did the king's decree in Daniel 6 require everyone to do?
The king's decree required all people to pray and bow the knee exclusively to the king of the Medes and Persians. It was engineered by those who hated Daniel and knew his prayer habits, though the king was unaware of their motive when he signed it.
Les explains that the decree was prompted by those who hated Daniel and knew his prayer habits. They got the king to sign it unbeknown to him, requiring everyone to pray and bow the knee only to the king of the Medes and Persians. This placed Daniel on the outside. Les uses this setting to address the basic tenet of prayer, saying the Christian community needs to come back to prayer in the day in which we live.
