Praise be to the name of God for ever and ever; wisdom and power are his.

Daniel 2:17-30
Daniel urged his three friends to plead for mercy from the God of heaven concerning this mystery.
Daniel replied to the king, 'No one can explain to the mystery the king has asked about, but there is a God in heaven who reveals mysteries.'
The dream showed king of Babylonia what is coming to happen.
"As for me, this mystery has been revealed to me, not because I have greater wisdom than other living men, but so that you, O king, may know the interpretation and that you may understand what went through your mind."
Daniel praised the God of heaven, " Praise be to the name of God for ever and ever; wisdom and power are his. He gives wisdom to the wise and knowledge to the discerning. He reveals deep and hidden things; he knows what lies in darkness, and light dwells with him.
Why?
Daniel knew God has the wisdom so he urged his friend pray for mercy from the  God. Many believers prayer is more quick reach to the Lord.
Ask for Christians together to pray has the one mind and one spirit with us.
Daniel did not forget that is the Lord revealed the mystery to him, no his wise or his ability, it is the power and mercy of the power came upon him. Don't steal the honor of the Lord!
God shows what is to come through the dream, or through bible, or through prophet, or directly tell us, or some significant signs.
How?
Pray to the Lord gives me the wisdom and mercy. He is mighty God, do not forget what God has done on me.
