“He replied, ‘I tell you that to everyone who has, more will be given, but as for the one who has nothing, even what they have will be taken away. But those enemies of mine who did not want me to be king over them—bring them here and kill them in front of me.’” Luke 19:26-27
Taken out of context, the words above by Jesus seem quite brutal. However, he was telling a story of a harsh king and how he would react if someone disobeyed his orders.
The point of the story was not to say that Jesus wants all non-believers killed. The point of the story was to talk about the responsibility a follower of Christ has with the gifts, talents and opportunities they have been given. In the story, the king gives three servants different amounts of money and tells them to invest the money, making it profitable.
Two servants double the money given to them. One hides it. The king is displeased with the last one's response, pointing out that if you aren't obedient to the king, then you don't want him to be your king.
If Jesus is being tough, it's on believers, not on non-believers.
So not knowing the context, this would seem like harsh words from Jesus. In context, we see he is a quoting a harsh king from a story towards his own followers.
