Luke 11: 14-23
Now he was casting out a demon that was mute. When the demon had gone out, the mute man spoke, and the people marveled. But some of them said, “He casts out demons by Beelzebul, the prince of demons,” while others, to test him, kept seeking from him a sign from heaven.But he, knowing their thoughts, said to them, “Every kingdom divided against itself is laid waste, and a divided household falls. And if Satan also is divided against himself, how will his kingdom stand? For you say that I cast out demons by Beelzebul. And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore they will be your judges. But if it is by the finger of God that I cast out demons, then the kingdom of God has come upon you. When a strong man, fully armed, guards his own palace, his goods are safe; but when one stronger than he attacks him and overcomes him, he takes away his armor in which he trusted and divides his spoil. WHOEVER IS NOT WITH ME IS AGAINST ME, and whoever does not gather with me scatters.
Luke 9 :49-50
John answered, “Master, we saw someone casting out demons in your name, and we tried to stop him, because he does not follow with us.” But Jesus said to him, “Do not stop him, FOR THE ONE WHO IS NOT AGAINST YOU IS FOR YOU.”
In my other article on the same subject, I shared that for matter of truth, Christians should have unity but for matter of conscience, we can have liberty.
Here is another example from the above 2 Scriptural passages concerning matter of truth and matter of conscience. You will notice that for matter of truth concerning the Personhood of our Lord in Luke 11:23, there is no liberty to disagree but strict adherence. “Whoever is not with Me is against Me.”
But for matter of conscience concerning Christian service, such as casting out of demons in Luke 9:50, there can be some liberty to agree to disagree. “(Though not with you), the one who is not against you is for you.”
