Matthew 12:22-32
22 Then a demon-possessed man who was blind and mute was brought to Jesus, and He healed him, so that the mute man both spoke and saw. 23 All the people wondered in amazement, and said, “Could this be the Son of David (the Messiah)?”
24 But the Pharisees heard it and said, “This man casts out demons only by [the help of] Beelzebul (Satan) the prince of the demons.”
25 Knowing their thoughts Jesus said to them, “Any kingdom that is divided against itself is being laid waste; and no city or house divided against itself will [continue to] stand. 26 If Satan casts out Satan [that is, his demons], he has become divided against himself and disunited; how then will his kingdom stand? 27 If I cast out the demons by [the help of] Beelzebul (Satan), by whom do your sons drive them out? For this reason they will be your judges. 28 But if it is by the Spirit of God that I cast out the demons, then the kingdom of God has come upon you [before you expected it]. 29 Or how can anyone go into a strong man’s house and steal his property unless he first overpowers and ties up the strong man? Then he will ransack and rob his house. 30 He who is not with Me [once and for all on My side] is against Me; and he who does not [unequivocally] gather with Me scatters. 31 “Therefore I say to you, every sin and blasphemy [every evil, abusive, injurious speaking, or indignity against sacred things] will be forgiven people, but blasphemy against the [Holy] Spirit will not be forgiven. 32 Whoever speaks a word against the Son of Man will be forgiven; but whoever speaks against the Holy Spirit [by attributing the miracles done by Me to Satan] will not be forgiven, either in this age or in the age to come.
Mark 3:20-30
20 Then He came to a house [in Capernaum], and a crowd formed again, so [many people] that Jesus and His disciples could not even eat a meal [together]. 21 When His own family heard this they went to take custody of Him; for they were saying, “He is out of His mind.”
22 The scribes who came down from Jerusalem were saying, “He is possessed by Beelzebul (Satan),” and “He is driving out the demons by the [power of the] ruler of the demons.”
23 So He called them to Himself and spoke to them in parables, “How can Satan drive out Satan? 24 If a kingdom is divided [split into factions and rebelling] against itself, that kingdom cannot stand. 25 And if a house is divided against itself, that house cannot stand. 26 And if Satan has risen up against himself and is divided, he cannot stand, but is coming to an end.
27 But no one can go into a strong man’s house and steal his property unless he first overpowers and ties up the strong man, and then he will ransack and rob his house. 28 “I assure you and most solemnly say to you, all sins will be forgiven the sons of men, and all the abusive and blasphemous things they say; 29 but whoever blasphemes against the Holy Spirit and His power [by attributing the miracles done by Me to Satan] never has forgiveness, but is guilty of an everlasting sin [a sin which is unforgivable in this present age as well as in the age to come]”— 30 [Jesus said this] because the scribes and Pharisees were [attributing His miracles to Satan by] saying, “He has an unclean spirit.”
Luke 11:14-23
14 And [at another time] Jesus was casting out a demon, and it was [controlling a man so as to make him] mute; when the demon had gone out, the mute man spoke. And the crowds were awed. 15 But some of them said, “He drives out demons by [the power of] Beelzebul (Satan), the ruler of the demons.” 16 Others, trying to test Him, were demanding of Him a sign from heaven.
17 But He, well aware of their thoughts and purpose, said to them, “Every kingdom divided against itself is doomed to destruction; and a house divided against itself falls. 18 If Satan also is divided against himself, how will his kingdom stand and continue to survive? For you are saying that I drive out demons by [the power of] Beelzebul. 19 Now if I drive out the demons by Beelzebul, by whom do your sons [the Jewish exorcists] drive them out? For this reason they will be your judges. 20 But if I drive out the demons by the finger of God, then the kingdom of God has already come upon you. 21 When the strong man, fully armed, guards his own house, his belongings are undisturbed and secure. 22 But when someone stronger than he attacks and overpowers him, he robs him of all his armor on which he had relied and divides his [goods as] spoil. 23 He who is not with Me [believing in Me as Lord and Savior] is against Me [there is no impartial position]; and he who does not gather with Me [assisting in My ministry], scatters.
