When Jesus had driven out a demon, some of the crowd said:
“By the power of Beelzebul, the prince of demons,
he drives out demons.”
Others, to test him, asked him for a sign from heaven.
But he knew their thoughts and said to them,
“Every kingdom divided against itself will be laid waste
and house will fall against house.
And if Satan is divided against himself, how will his kingdom stand?
For you say that it is by Beelzebul that I drive out demons.
If I, then, drive out demons by Beelzebul,
by whom do your own people drive them out?
Therefore they will be your judges.
But if it is by the finger of God that I drive out demons,
then the Kingdom of God has come upon you.
When a strong man fully armed guards his palace,
his possessions are safe.
But when one stronger than he attacks and overcomes him,
he takes away the armor on which he relied
and distributes the spoils.
Whoever is not with me is against me,
and whoever does not gather with me scatters.
“When an unclean spirit goes out of someone,
it roams through arid regions searching for rest
but, finding none, it says,
‘I shall return to my home from which I came.’
But upon returning, it finds it swept clean and put in order.
Then it goes and brings back seven other spirits
more wicked than itself who move in and dwell there,
and the last condition of that man is worse than the first.

God and his Word is the source of our protection and security
What is the point of Jesus’ grim story about a vacant house being occupied by an evil force? It is not enough to banish evil thoughts and habits from our lives. We must also fill the void with God who is the source of all that is good, wholesome, true, and life-giving for us. Augustine of Hippo said that our lives have a God-shaped void which only God can fill satisfactorily. If we attempt to leave it vacant or to fill it with something else, we will end up being in a worse state in the end.
What do you fill the void in your life with? The Lord Jesus wants to fill our hearts and minds with the power of his life-giving word and healing love. Jesus makes it very clear that there are no neutral parties in this world. We are either for Jesus or against him, for the kingdom of God or against it. There are ultimately only two kingdoms which stand in opposition to one another – the kingdom of God and the kingdom of darkness which is under the rule of Satan. If we disobey God’s word, we open to door to the power of sin and Satan.
Is Jesus the Lord of your mind, heart, and home?
If we want to live in true freedom, then our “house” (the inner core of our true being) must be occupied by Jesus where he is enthroned as Lord and Savior. The Lord assures us of his protection from spiritual harm and he gives us the help and strength we need to resist the devil and his lies (James 4:7). “Because you have made the Lord your refuge, the Most High your habitation, no evil shall befall you, no scourge come near your tent. For he will give his angels charge of you to guard you in all your ways”(Psalm 91:9-11). Do you know the peace and security of a life submitted to God and his word?
“Lord Jesus, be the ruler of my heart and the master of my home. May there be nothing in my life that is not under your lordship.”
