It will be the Word which puts the enemy on the run Luk 4:4 .   

Unfortunately, most pray-ers are cowards because they can do it in their closets Mat 5:16 .   

Obeyers are conquerors Phi 2:8 Rom 8:37 .   

Jesus obeyed all day and He prayed at night.   

Peter obeyed all day and prayed at night.   

Paul obeyed all day and prayed at night.   

If you are burning daylight praying you are not working.   

I must work the works of him that sent me, while it is day: the night comes, when no man can work. Joh 9:4 I believe `the night` is when there is so much unbelief that there is no faith for salvation, healing, deliverance or victory.

Prayer Is To Prepare.   It is not to give God orders or to bog Him down with a laundry list of 'wishes'.   

You don't put on the Whole Armour Of God and sit on a couch or go into your prayer closet.
