Daniel 6:1-4 (ESV)
It pleased Darius to set over the kingdom 120 satraps, to be throughout the whole kingdom; 2 and over them three high officials, of whom Daniel was one, to whom these satraps should give account, so that the king might suffer no loss. 3 Then this Daniel became distinguished above all the other high officials and satraps, because an excellent spirit was in him. And the king planned to set him over the whole kingdom. 4 Then the high officials and the satraps sought to find a ground for complaint against Daniel with regard to the kingdom, but they could find no ground for complaint or any fault, because he was faithful, and no error or fault was found in him.

Daniel had a reputation built on decades of faithfulness to God, that spanned through three different monarchies.

Daniel represents what it looks like to be above reproach.

1 Timothy 3:1-2a
The saying is trustworthy: If anyone aspires to the office of overseer, he desires a noble task. 2 Therefore an overseer must be above reproach…

Daniel 6:6-7
Then these high officials and satraps came by agreement to the king and said to him, “O King Darius, live forever! 7 All the high officials of the kingdom, the prefects and the satraps, the counselors and the governors are agreed that the king should establish an ordinance and enforce an injunction, that whoever makes petition to any god or man for thirty days, except to you, O king, shall be cast into the den of lions.”

Daniel’s prayer life was so consistent that his enemies knew they only needed a 30-day period to entrap Daniel.

Prayer is one of the simplest acts of obedience that we should be taking part in daily.

Mark 1:35
And rising very early in the morning, while it was still dark, he departed and went out to a desolate place, and there he prayed.

Luke 11:1
Now Jesus was praying in a certain place, and when he finished, one of his disciples said to him, “Lord, teach us to pray, as John taught his disciples.”

When Daniel discovered there was a law forbidding him to pray, he simply continued his routine of prayer and obedience.

Daniel 6:15-16
Then these men came by agreement to the king and said to the king, “Know, O king, that it is a law of the Medes and Persians that no injunction or ordinance that the king establishes can be changed.” 16 Then the king commanded, and Daniel was brought and cast into the den of lions. The king declared to Daniel, “May your God, whom you serve continually, deliver you!”

Even the pagan king recognized how consistent and committed Daniel was to his relationship with God.

Daniel 6:19-23
Then, at break of day, the king arose and went in haste to the den of lions. 20 As he came near to the den where Daniel was, he cried out in a tone of anguish. The king declared to Daniel, “O Daniel, servant of the living God, has your God, whom you serve continually, been able to deliver you from the lions?” 21 Then Daniel said to the king, “O king, live forever! 22 My God sent his angel and shut the lions’ mouths, and they have not harmed me, because I was found blameless before him; and also before you, O king, I have done no harm.” 23 Then the king was exceedingly glad, and commanded that Daniel be taken up out of the den. So Daniel was taken up out of the den, and no kind of harm was found on him, because he had trusted in his God.

In order to survive and thrive in Babylon, believers have to trust in God.

Acts 12:5-7
So Peter was kept in prison, but earnest prayer for him was made to God by the church. 6 Now when Herod was about to bring him out, on that very night, Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison. 7 And behold, an angel of the Lord stood next to him, and a light shone in the cell. He struck Peter on the side and woke him, saying, “Get up quickly.” And the chains fell off his hands.

“The angel fetched Peter out of prison, but it was prayer that fetched the angel.” - Thomas Watson

Sometimes prayer brings deliverance, but it always brings peace.
