The persecution of Christians is already going on in Europe itself by politicians and bureaucrats of western societies. If a Muslim or a homosexual has a case against Christian beliefs then guess who always loses? The Christian who does not work on the Sabbath is victimised and rejected by society. We have observed cases against Christians who refuse to acknowledge unbiblical practises in society, and today they are penalised by the societies courts, when in fact historically these practices were condemned by society.
But Christians expect worldly society to persecute us. Matthew 5:11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
