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.

Satan is as deadly as Cancer
Ephesians 6

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. v12

There is certainly no doubt that evil is real, on the "prowl", powerful, and very deceptive - we must protect ourselves.  The devotion today devotes little focus on how.  Yet the verses before and after verse 12 speak directly to how we can protect ourselves and Romans 12 and other verses get more specific in this regard.

Finally, be strong in the Lord and in his mighty power. Put on the full armor of God, so that you can take your stand against the devil’s schemes. Ephesians 6:10-11

...

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. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God.

 

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. Ephesians 6:13-18

...
Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will. Romans 12:2

 ...

For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 2 Corinthians 10:3-5

We MUST be in the word, stay rooted to Him, etc. - see also Deuteronomy 6, John 15.

My Prayer: Lord Jesus, You alone are my protector, in all things and all circumstances.  Thank You for You protect me daily...I know You are slow to anger and abounding in love...Thank You!  I am not worth such protection and love yet You are full of mercy anyway.  I often fail to be the man You intend for me - I should be sharing the Good News about You all the time yet I don't - please forgive me.  Help me turn from such sin and towards You.  Help me be more bold.  Help me love You with all of my heart, soul, mind and strength.  Help me love others as You do.  Help me grow in my faith.  Give me strength.  Give Lisa strength.  Please heal and cure her of her cancer and the side effects from chemo and radiation.  Help me lead and serve Lisa, Zach and Dustin...and serve You!  Help me understand, be obedient to, and apply Your message for me today and every day.
