Satan is a relentless adversary
1 Peter 5:7-9 ESV
6 Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you, 7 casting all your anxieties on him, because he cares for you. 8 Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. 9 Resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world.
