“Blessed are they which are persecuted for righteousness’ sake, for theirs is the Kingdom of Heaven.”
For righteousness’ sake, is meant to live righteously according to the commandments of God, and resolutely fulfilling Christian obligations. Persecuted — for their righteous and pious life, they suffer oppression, persecution, privation and adversity at the hands of the unrighteous enemies of truth and goodness, but nothing can cause them to waver from the truth.
Persecution is inevitable for Christians living according to the Gospel’s righteousness, because evil people detest righteousness, as truth exposes their evil deeds, and always persecute people who stand up for the truth. The Only-begotten Son of God, Jesus Christ, was Himself crucified by haters of God’s truth. For all His followers He predicted: // they have persecuted Me, they will also persecute you (John 15:20). All that will live godly in Christ Jesus shall suffer persecution, says the Apostle Paul. In order to endure persecution patiently for righteousness’ sake, a person must have love for the truth, be steadfast and firm in virtuous living, have courage and patience, and faith and hope in the help and protection of God. To those persecuted for righteousness’ sake, for their struggles in confessing the truth, the Lord promises the Kingdom of Heaven, spiritual triumph, joy and blessedness in the heavenly dwellings of the future eternal life.
