Peace! Be strong now; be strong

Daniel 10:11-11:1
Angle Michael was delayed 21 days.
“Daniel, you who are highly esteemed, consider carefully the words I am about to speak to you, and stand up, for I have now been sent to you.”
I am overcome with anguish because of the vision, my lord, and I feel very weak.
Again the one who looked like a man touched me and gave me strength.
“Do not be afraid, you who are highly esteemed,” he said. “Peace! Be strong now; be strong.” When he spoke to me, I was strengthened and said, “Speak, my lord, since you have given me strength.”  
He is given insight into the continual battle raging in the spiritual realm between those protecting God's people and those bent on their destruction. 
Michael is the special guardian angel of the Jewish people. The 'princes' in this chapter are patron(保護人) angels of the various nations.
Why?
Daniel is highly esteemed people before the Lord. so the vision were showed to him.
Angle come to encourage those who pray to the Lord.
Saw the vision Daniel was anguish for there were fear and battle of spirit. 
Knowing the future does not mean good to us, but under the blessing of the Lord we can stand firm when vision is showing to us.
How?
Am I frustrate when my prayer has not been answered by the Lord? Focus on the Lord who has heard my prayer and has sent angle to give me the answer!  Wait and be strong!
