In fact, no one can enter a strong man’s house and carry off his possessions unless he first ties up the strong man. Then he can rob his house (Mark 3:27).
Though most of us don’t understand much of it, the Bible makes it clear that there is an unseen world around us that somehow influences this world. This is Jesus’ subject in this passage of Scripture in Mark 3.
The New Testament suggests a cosmology of angelic beings that exercise their power over various entities within our world. There seems to be a distinction in Paul’s mind between the various angelic beings that he describes in Colossians 1:16, “thrones or powers or rulers or authorities.” What exactly the various beings influence is unclear, but there is ample evidence to suggest that some of these beings influence individuals (for good or for bad) and some influence nations or perhaps, ethnic groups. In a vision the prophet Daniel describes one of these angelic beings as “the prince of Persia” (10:13), suggesting that his influence was over that whole nation or people.
When Jesus was speaking in Mark 3, it appears that He was referring to this unseen cosmology because it was in the context of a discussion about Satan’s influence in this world. Satan is described as “the god of this world” in 2 Cor. 4:4, and the metaphor is changed to a house in Mark 3. But in both pictures Satan and his angelic majesties are in view and the reference to “the strong man” that must be bound is a reference to Satan or one of his demons. Jesus (and His body, the Church) are seeking to “carry off his possessions,” the people that are still under his dominion.
The exact meaning of this statement, then, hinges on what it means to “bind the strong man.” Not only, it would appear, does the unseen world have influence over ours, but we in this world can exert some influence over that world as well, probably through prayer, fasting and other spiritual disciplines. In my opinion these disciplines are the means by which we become partners with Him in the work of the kingdom.
I suggest that one of the ways we are to “bind the strong man” is by prayer for the people groups that are still unreached in our world. Satan is the one who has “blinded the minds of the unbelieving” (see again 2 Cor. 4:4). By “binding” him, then, we would release these people from the blindness so that they can see Christ and turn to Him.
The Bible is clear in Matthew 24:14 that Jesus will return when the last person is reached with the Gospel. By binding Satan through prayer, we are partnering with Him in the great cause of world evangelization, and hastening His return.
