Yes, there is no middle ground: either following Jesus and resisting the devil, or following the devil and rejecting Jesus. In Matthew 12:30 Jesus sharply judges the so-called critical neutrality of the Pharisees as showing their opposition to him and alignment with Satan.
Yes, for it is impossible to remain neutral. There is no middle ground, for either you follow Jesus and resist the devil, or you follow the devil and stand opposed to the Lord Jesus. In Matthew 12:30 Jesus pronounces a sharp judgment on the so-called critical neutrality of the Pharisees.1
Matthew 12:30 shows that there are two parties who are irreconcilable opponents: Jesus and Satan. God and his kingdom, which Jesus brings, stand opposed to the devil and his kingdom. For if something is not done for the devil, then it is done for God. The parable reduces all things to only two powers. Jesus appears as the conqueror, that is how he revealed himself; he acts on his own authority. Everyone must make a choice in the struggle between these two kingdoms, for Christ here shows that neutrality is impossible. Whoever, like the Pharisees, declares that he does not wish to stand on the side of Christ, thereby automatically takes the side of Satan, for there are no other powers.2
30 Celui qui n'est pas avec moi est contre moi, et celui qui n'assemble pas avec moi disperse.
