The only powerful weapons we have is our relationship with God, truth in His word and prayer. He spoke and there was creation, the heavens and the earth. He spoke again and He created us. Nothing is impossible with Him. We cannot give away our faith, hope and joy. It is rightfully ours because we belong to a heavenly Kingdom and are children of God. We will see God's hand move on our behalf to bring Himself glory and to break the chains of darkness. This battle is not ours but His.
2 Chronicles 20:15 (KJV)
15 And he said, Hearken ye, all Judah, and ye inhabitants of Jerusalem, and thou king Jehoshaphat, Thus saith the Lord unto you, Be not afraid nor dismayed by reason of this great multitude; for the battle is not yours, but God's.
