Many Christians don't really understand, that our enemy is highly intelligent. Or understand that he actually preys on us-- just as he did with Jesus--at "the opportune time"…
"When the devil had finished all this tempting, he left him until an opportune time." (NIV Luke 4:13)
Like Jesus, when we're tired and hungry--and hunger takes many forms--that's when the enemy goes in for the attack. After reflection, I can see how this enemy tactic has been played out often in my own life. If we also realize, that:"Your enemy the devil prowls around like a roaring lion looking for someone to devour." (NIV 1Peter 5:8)… well it can all get pretty scary. Thankfully, God provides us with the best ammunition against worrying about all this, because...
...the one who is in you is greater than the one who is in the world" (NIV 1John 4:4)
It's widely known, how good for our physical health it is, getting proper rest and eating nutritious food. Similarly, when we feed on Jesus through His Word, this helps our souls to stay rested, hydrated and well fed. Then we can feel stronger to fend off the attack of our enemy.
The concept of "feeding body and soul" seems almost redundant! I think of God as an "Efficiency Expert"…per this example…When you feed your body-you're helping to feed your soul, too!
I love You, Holy Trinity (another example of efficiency-"3 in 1"!)
"They feast on the abundance of your house; you give them drink from your river of delights."
(NIV Psalm 36-8)
