For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
Ephesians 6:12

The devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. “All this I will give you,” he said, “if you will bow down and worship me.”
Matthew 4:8-9

But even the archangel Michael, when he was disputing with the devil about the body of Moses, did not dare to bring a slanderous accusation against him, but said, “The Lord rebuke you!”
Jude 1:9

So we say with confidence, “The Lord is my helper; I will not be afraid.  What can man do to me?”
Hebrews 13:6

The Lord is my light and my salvation— whom shall I fear?  The Lord is the stronghold of my life— of whom shall I be afraid?  When evil men advance against me to devour my flesh, when my enemies and my foes attack me, they will stumble and fall.   Though an army besiege me, my heart will not fear; though war break out against me, even then will I be confident.
Psalm 27:1-3

Some men came and told Jehoshaphat, “A vast army is coming against you from Edom, from the other side of the Sea. It is already in Hazazon Tamar” (that is, En Gedi).  Alarmed, Jehoshaphat resolved to inquire of the Lord, and he proclaimed a fast for all Judah.  The people of Judah came together to seek help from the Lord; indeed, they came from every town in Judah to seek him.
2 Chronicles 20:2-4

Then Jehoshaphat stood up in the assembly of Judah and Jerusalem at the temple of the Lord in the front of the new courtyard and said: “O Lord, God of our fathers, are you not the God who is in heaven? You rule over all the kingdoms of the nations. POWER AND MIGHT ARE IN YOUR HAND, and no one can withstand you.  O our God, … we have no power to face this vast army that is attacking us. We do not know what to do, but our eyes are upon you.”
2 Chronicles 20:5-6,12

Five times I received from the Jews the forty lashes minus one.  Three times I was beaten with rods, once I was stoned, three times I was shipwrecked, I spent a night and a day in the open sea,  I have been constantly on the move. I have been in danger from rivers, in danger from bandits, in danger from my own countrymen, in danger from Gentiles; in danger in the city, in danger in the country, in danger at sea; and in danger from false brothers.  I have labored and toiled and have often gone without sleep; I have known hunger and thirst and have often gone without food; I have been cold and naked.
2 Corinthians 11:24-27

And we know that in all things God works for the good of those who love him, who have been called according to HIS purpose. What, then, shall we say in response to this? IF God is for us, who can be against us? 
Romans 8:28,31 

Be strong in the Lord and in the power of HIS might.
Ephesians 6:10
