'Reason' in the Bible

And if I drive out demons by Beelzebul, who is it your sons drive them out by? For this reason they will be your judges.

For this reason I speak to them in parables, because looking they do not see, and hearing they do not listen or understand.

For this reason, the kingdom of heaven can be compared to a king who wanted to settle accounts with his slaves.

and He also said:“For this reason a man will leavehis father and motherand be joined to his wife,and the two will become one flesh?
