I want you to hear what Jesus said about peace because many people have not understood the mission of Jesus.
Luke 12:51-53 New King James Version (NKJV)
51 Do you suppose that I came to give peace on earth? I tell you, not at all, but rather division. 52 For from now on five in one house will be divided: three against two, and two against three. 53 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.”
Now this is Jesus declaring that did not come to give peace on earth because earth was under the authority of Satan and His message of love would bring division even among families and it certainly did in His own family.
