Daniel 6:10 Now when Daniel learned that the decree had been published, he went home to his upstairs room where the windows opened toward Jerusalem. Three times a day he got down on his knees and prayed, giving thanks to his God, just as he had done before.
Daniel did not follow the rules of the land in this matter because he knew in his heart it was against everything he had learned about God.
God is never going to support any law from any land which prohibits people praying openly to Him; Daniel continued to pray openly (he continued to leave his window open just as he had always done)
We need to follow this example and the example laid down by the disciples and lift up our prayers to God ever day and always; He will never stop listening!
