The How Plus The 4 W's Of Prayer

God  declares  our  prayers  are so precious and beautiful to him to such an extent; he has angels posted  while we  are praying  who collects them (Revelation 5:8) and places our prayers in golden vials (huge).

When we pray; we  are enforcing  the  judgments Jesus  Christ  passed  on  the  devil  at  Calvary.  Prayer is God’s gift of power to us to deal decisive, effective and definitive defeats to the intents of the devil.  We pray from a standpoint of victory.

Michael  the  Archangel  when contending with the devil demonstrated the best way to deal an effective, decisive and definitive defeat against the devil is to rely on God's power and say “The Lord rebuke thee.” (Jude 9)  

Again, when the devil tried to prevent the answer to Daniel's  prayer from being delivered to him; the  Archangel Michael showed up and simply “took” without a struggle the answer and delivered the answer to Daniel.  (Daniel 10:13)
