This cartoon from AgnusDay reminds me of two things:
Satan was defeated at the cross!
Sometimes we need to be reminded that Satan was defeated at the cross!
Therefore humble yourselves under the mighty hand of God, that He may exalt you at the proper time, casting all your anxiety on Him, because He cares for you. Be of sober spirit, be on the alert. Your adversary, the devil, prowls around like a roaring lion, seeking someone to devour. But resist him, firm in your faith, knowing that the same experiences of suffering are being accomplished by your brethren who are in the world. After you have suffered for a little while, the God of all grace, who called you to His eternal glory in Christ, will Himself perfect, confirm, strengthen and establish you. To Him be dominion forever and ever. Amen. (1 Peter 5:6-11)
