The word “wiles” in Ephesians 6:11 can be defined as “devious or cunning strategies employed in manipulating or persuading someone to do what one wants.” Synonyms of “wiles” include tricks, ruses, ploys, schemes, maneuvers, gambits, subterfuges, cunning strategies, devices or contrivances employing guile, artfulness, cunning, or craftiness.

All of those words can be used when considering the work of Satan in his attempts to negate or subvert the will and work of God. When contemplating the range of ways Satan acts, it is no wonder that Peter admonishes us to be “sober” and “vigilant” (1 Peter 5:8). Jesus described Satan as a murderer and a liar and the father of lies (John 8:44). When he speaks or acts, he lies—and lying is consistent with his character; it is his native language. Satan does not have the power that God has; he is not God’s opposite. Rather, he is evil personified and will do whatever he can to trick, ensnare, and deceive the child of God.

Live a spiritually alert life in Christ, clothed in the spiritual armor of God. In Him is our protection found. 

Satan trembles when he sees the weakest saint upon his knees.
William Cowper
