“Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven.”
This verse is part of the Lord’s teaching known as the Beatitudes. It is an encouragement to those who are under an oppressive, unjust, and cruel treatment because of their faith in Jesus.
Without such a great promise — to be blessed for being subject of persecution — one would ask himself “Why am I suffering? Is it in vain?” But the words of Jesus are a promise that standing for the righteousness of God in this world has a great reward — the kingdom of heaven. In God’s kingdom eternal righteousness and justice reign. Those persecuted on earth will inherit this kingdom — it is theirs, it is their home, their inheritance. Those formerly mistreated for being citizen of this eternal kingdom will now live in it, they will be its rulers.
Standing with righteousness against the unrighteous, and paying a price has a great reward in waiting.
A second notion is that wherever there is a kingdom there is a system of justice. The justice of the eternal kingdom of God is founded on the just and eternal God. The suffering of those who stood for the name of God and His Son, under the persecution of the wicked kingdoms of this world, will be redeemed with the reward of heaven. For those who are faithful justice will mean their sacrifice will be their badge of honor before the King of kings.
