The book that I read all of this in says, to ponder the fact that God has a life of blessings for you, and remember that being comes before doing for what we do is always determined by who we are. In the believers case, whose are you.
:6 Blessed are those who hunger and thirst for righteousness, for they shall be filled.
It is not those who are hungering and thirsting for happiness who are being satisfied. It is those who strive for the righteousness of Christ in their own lives.
Someone who has been shown mercy and is hungering for righteousness, is someone who is showing mercy.
:8 Blessed are the pure of heart, for they shall see God.
It becomes as natural as water running down hill for the one who is pursuing God to have a pure heart in motives and morals.
:9 Blessed are the peacemakers, for they shall be called sons of God.
God says peacemakers, not peace lovers. Someone who tries to sow seeds of discord, is someone who is not thirsting for the things of God. Someone who is after God’s heart, is someone living in love and unity with those around them.
:10 Blessed are those who are persecuted for righteousness.
Someone who is never confronted by spiritual obstacles, is someone not hungry for the things of God. If we are not meeting the devil head on from time to time, we are most likely going the same way he is head.
