The final petition of the “Our Father” builds upon the previous one about not falling prey to temptation.
The tempter, the one who hates us and wants to destroy our relationship with God, is Satan. This fallen angel is literally our enemy, for Satan comes from the Hebrew for “adversary” or “accuser.”
Having rebelled against God, the Evil One is bound for eternal damnation, and like a supernatural serial killer, he is out to bring as many people down to hell with him as possible. Satan tricked our first parents into sin, thus unleashing suffering, death, and corruption into God’s originally pristine creation. The Evil One has continued to make war against God – and His people – ever since.
As a result, we are engaged in a spiritual battle for our immortal souls.
This is not to terrify us, for Christ has utterly and irrevocably conquered through His Passion, Death, and Resurrection, and His victory will be made manifest at the end of time. We are safe as long as we remain in His protecting arms.
But at the same time, we must be aware that the devil is looking for opportunities to tear us away from God. Never open a door to evil; dabbling in the occult leads to real spiritual harm.
Let us pray as Jesus taught us, that we may be delivered from evil – from the Evil One, and from all of the tragedies, injustices, and disasters that beset our fallen world.
