God gives us what we need to defend ourselves.
Read: Ephesians 6:13-17
Therefore, put on every piece of God’s armor so you will be able to resist the enemy in the time of evil. Then after the battle you will still be standing firm.14 Stand your ground, putting on the belt of truth and the body armor of God’s righteousness. 15 For shoes, put on the peace that comes from the Good News so that you will be fully prepared.[a] 16 In addition to all of these, hold up the shield of faith to stop the fiery arrows of the devil.[b] 17 Put on salvation as your helmet, and take the sword of the Spirit, which is the word of God.
