Mark 3:27 “No man can enter into a strong man’s house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.”
The Greek word for spoil occurs in two forms, Depose and harapzo, which denotes “an intensive spoiling, plunder and snatching away.” In (Lk. 11-22), the Greek word Skulon, conveys “arms stripped from a foe.” Putting it simply, Satan is stripped of his weapons, (Lk. 11:21,22. The Greek word Deo means literally tie or fasten, to arrest or paralyze. Everything that he has stolen is reclaimed. Moreover, Christians aggressively binding the power of demons, prohibits them from the carry-forward their assignments.
Gary Kinnaman develops this theological foundation for binding: “The use of the phrase binding did not, in fact, originate with Jesus. Binding was a frequent expression of first century Jewish rabbinical dialect. According to Alexander Bruce in The Expositor’s Greek New Testament to bind and loose (Greek, deo and luo) meant simply “to prohibit and to permit,” that is to establish. The Jewish religious authorities at the time of Christ retained the right to establish guidelines for or keys to, religious practices and social interaction.
But deo (to bind, tie) also expresses supernatural control. In (Lk. 12:15-16), Jesus rebuked a Jewish leader, “You hypocrites! Doesn’t each of you on the Sabbath untie {Greek Luo, loose} his ox or donkey from the stall and lead it out to give it water? Should not this woman, a daughter of Abraham, whom Satan has kept bound {Greek: deo, bind} for eighteen long years, be set free {Greek: Luo, loose} on the Sabbath day from what bound her.”
The Jewish leaders in the day of Christ understood only the natural part of binding or locking, and He was showing them through the encounter with the woman bound by infirmity that binding and locking had a supernatural side. Notice that Jesus said specifically that it was Satan who bound the woman. Observe how untestable that the Jewish leaders were and also furious with Jesus for telling His disciples that they had the authority to bind and loose since they were not part of the prescribed Jewish religious/political system. The Jewish leaders felt that He was giving them authority that He had no right to give. They did not understand that Jesus was giving them authority in the unseen realm in heavenly places. This is the realm where the real binding and locking occur and from which all things on the earth can be bound or loosed–disallowed or allowed.
