And he could not sleep. At the first light of dawn, the king got up and hurried to the lions' den. Daniel's piety made a big impression on the king. It appears that from his 13th birthday for the next 75 years Daniel kept making decisions that built faith in his life. Spiritual disciplines done from the heart can attract people to our faith in God.
Spiritual disciplines done in a legalistic fashion make our faith stink.
I love Daniel's bold declaration of faith. My God sent his angel, and he shut the mouths of the lions. They have not hurt me, because I was found innocent in his sight. Nor have I ever done any wrong before you, O king. The king was overjoyed and gave orders to lift Daniel out of the den.
