Rev 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
Rev 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
We are in a spiritual Battle along with the angels
It is when we pray that we have the victory
Dan 10:12-13 Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words. (13) But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.
Here we see that when Daniel prayed immediately it was answered but it took 21 days of intense prayer to win the battle in the heavenlies
Joh 10:10 The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
Bible says that satan comes to Steal kill and destroy
In these last days He is out to kill even a believer
He brings problems in our lives that a moment we think of even killing yourself
Jesus said he is a murderer from the beginning
Joh 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
There fell down many slain, because the war was of God.”
Warrior, fighting under the banner of the Lord Jesus, observe this verse with holy joy, for as it was in the days of old so is it now, if the war be of God the victory is sure. The sons of Reuben, and the Gadites, and the half tribe of Manasseh could barely muster five and forty thousand fighting men, and yet in their war with the Hagarites, they slew “men, an hundred thousand,” “for they cried to God in the battle, and he was entreated of them, because they put their trust in him.” The Lord saveth not by many nor by few; it is ours to go forth in Jehovah’s name if we be but a handful of men, for the Lord of Hosts is with us for our Captain. They did not neglect buckler, and sword, and bow, neither did they place their trust in these weapons; we must use all fitting means, but our confidence must rest in the Lord alone, for he is the sword and the shield of his people. The great reason of their extraordinary success lay in the fact that “the war was of God.” Beloved, in fighting with sin without and within, with error doctrinal or practical, with spiritual wickedness in high places or low places, with devils and the devil’s allies, you are waging Jehovah’s war, and unless he himself can be worsted, you need not fear defeat. Quail not before superior numbers, shrink not from difficulties or impossibilities, flinch not at wounds or death, smite with the two-edged sword of the Spirit, and the slain shall lie in heaps. The battle is the Lord’s and he will deliver his enemies into our hands. With steadfast foot, strong hand, dauntless heart, and flaming zeal, rush to the conflict, and the hosts of evil shall fly like chaff before the gale.
Stand up! stand up for Jesus!
The strife will not be long;
This day the noise of battle,
The next the victor’s song:
To him that overcometh,
A crown of life shall be;
He with the King of glory
Shall reign eternally.
