Opposition to the World Brings Hatred

“‘If the world hates you, you know that it has hated Me before it hated you. If you were of the world, the world would love its own; but because you are not of the world, but I chose you out of the world, therefore the world hates you'” (John 15:18-19).
Because they 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’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 “children of God above reproach in the midst of a crooked and perverse generation” (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 heartened by Jesus’ words, “You are the light of the world. A city set on a hill cannot be hidden” (Matt. 5:14).
