Daniel 10:12 Then said he unto me, Fear not, Daniel; for from the first day that thou didst set thy heart to understand, and to humble thyself before thy God, thy words were heard: and I am come for thy words’ sake. 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.

Look at answered prayer here, a humble prayer from Daniel yields results from God in spite of opposition from the enemy.   The enemy may slow prayer, but he cannot stop the answers.  God is God, He created the earth and the universe, eventually He will in every place in the universe be the LORD.  So don’t worry about a tiny little spot in the universe called earth where the enemy appears to have some temporary victory, eventually God will win.  At the end of the Bible God is on the throne and fully rulling in the universe and on this tiny earth.

Don’t ever forget in Psalms 24:1 The earth is Jehovah’s, and the fulness thereof; The world, and they that dwell therein.   2 For he hath founded it upon the seas, And established it upon the floods.
