John 15:18-19

18 If the world hate you, ye know that it hated me before it hated you. 19 If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.

Beloved, as redeemed People, we are not part of the world’s system, Christians …should expect it to hate and oppose them. If you’ve been a Christian for a while, you doubtless remember how soon you realized that you were no longer in step with the world’s culture. You were no longer comfortable with its philosophy. You no longer had the world’s desires and yearnings. You no longer felt good about doing some of the things the world takes for granted. In fact, you even felt constrained to speak
out against such things and urge unbelievers to turn from their sins and embrace Christ. All that opposition to worldliness, when added up, can and will result in hatred toward us from people in the world.
In John 15, the Greek word translated “world” (kosmos) refers to the world and it’s system of sin, which is devised by Satan and acted out by sinful people. The Devil and his angels sometimes make it even more difficult for us by subtly presenting their “religion” as if it were true. Such deception can lull us into complacency and leave us spiritually weak when persecution comes. Because of the world’s relentless opposition to God’s kingdom, it is crucial that we remember Christ’s call to stand for Him in our sinful society. The apostle Paul exhorts us to be “That ye may be blameless and harmless, the sons of God, without rebuke, in the midst of a crooked and perverse nation, among whom ye shine as lights in the world;” (Phil. 2:15). If we take Scripture seriously and prayerfully spend time in it daily, we will not be caught off guard when our faith is opposed. Instead, we will be moved by Jesus’ words, “You are the light of the world. A city set on a hill cannot be hidden” (Matt. 5:14).

Blessings!
