So then, be careful how you walk, not as unwise people but as wise, making the most of every opportunity because the days are evil. Ephesians 5:15,16

For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places. Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the evil times. Then after the battle, you will still be standing firm. Ephesian 6:12.13
