Pastor Adam Brock shows us key ways not only recognize what it looks like, but to authentically live it out. If you don't have a Bible, you can follow along in Ephesians.
So you can stand firm and do battle (Ephesians 6:10–13)
Finally, be strong in the Lord and in the strength of His might. Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. 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. Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm.
Ephesians 6:10–13
