Matthew 10:34–36 describes Jesus telling the disciples that He came not to bring peace to the world, but a sword. Jesus’ sword was never a literal one. In fact, when Peter took up a sword to defend Jesus in the Garden of Gethsemane, Jesus rebuked him and told him to put away his sword, "for all who draw the sword will die by the sword” (Matthew 26:52). Why then, did Jesus say, “Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword.” What kind of sword did Jesus come to bring?
It is inevitable that there will be conflict between good and evil, the Christ and the antichrist, the light and the darkness, the children of God (believers) and the children of the devil (those who refuse Christ). Conflict must arise between the two groups, and this can and does happen within a family in which some are believers and others are not. We should seek to be at peace with all men but should never forget that Jesus warned we will be hated for His sake. Because those who reject Him hate Him, they will hate His followers as well (John 15:18).
The language and rhetoric of the era in which the Bible was written allow for and actually cause different messages for different people depending on what is in their hearts. My heart is filled with His healing love. You are the only person who knows what is truly in your heart. I can only encourage you to seek His Truth.
