The armor of God

Ephesians 6:10-18

New International Version

10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. If you are not completely prepared, the enemy is very likely to knock you down and kill you. 

12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. I have other posts on if evil and the devil and angels and all that are real. Yeah, here's your sign. The struggle in the spiritual realm is very, very real. 

13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace.16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God.

18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people.

Always be having a conversation, a "pep talk" if you will, will God. Talking to Him, also known as prayer, is crucial to knowing what you're supposed to do on the battle field. 

Life is the battle field. If you are prepared with all the the things God has given you, you'll be prepared. This doesn't mean the devil won't beat you hard, but it does mean you'll be ready for the battle.
