The Beatitudes are steps leading to God’s Kingdom.
We all want mercy for ourselves and justice or fairness for others. We should want mercy for all. God gives us mercy and expects us to pass it on.
That which is in our heart results in words and deeds. Only the pure in heart will see God.
Most people want peace but few make peace in an active way and pursue it.
The worst form of unfairness is persecution for righteousness. Those who practice righteousness and are persecuted for that reason are on the way to the Kingdom
