What does John 15:18 mean?

As Christians, we should expect opposition and hatred from this world just as Jesus did. But remember this verse which serves as an encouragement for us to persevere in our faith while we stand firm in our beliefs and respond to hatred with love. And ultimately, our identity is rooted in Christ and it is through Him that we find the strength and purpose to go through the challenges of a world that may not always understand or accept our faith.
