Yes, Jesus is the Prince of Peace, but since He is the Creator, He brings peace on His terms, which many people do not accept. Therefore, they rebel against anyone preaching the peace that Jesus brings, and that in turn brings fire from Him, and it will cause division between those who accept Jesus and those who reject Him,

“I came to send fire on the earth, and how I wish it were already kindled! But I have a baptism to be baptized with, and how distressed I am till it is accomplished! Do you suppose that I came to give peace on earth? I tell you, not at all, but rather division. For from now on five in one house will be divided: three against two, and two against three. Father will be divided against son and son against father, mother against daughter and daughter against mother, mother-in-law against her daughter-in-law and daughter-in-law against her mother-in-law” (Luke 12.49–53).

Will you stand with Jesus even if it means that your family turns against you?
