Why Two parts:
The Beatitudes parts seem to be to provide the following:
Situation
Outcome or "hope"
For example in the first Beatitude it says "blessed or happy are the poor in spirit, for theirs in the kingdom of God or Heaven (depending on translation.) The first part is the listener situation. In this case it is the state of being poor in spirit. In others it is the state of mourning. But the second part provides us with hope, with outcome. If the listeners is mourning they will be comforted, if you thirst and hunger for righteousness, you will be given food to satisfy you.
Why use Paradox
Jesus was speaking to both the learned and the unlearned. His technique was to ensure that all would be able to understand. Talk about paradox! If you are meek, you will inherit the earth!! That is really a wake up call. People listening could not help but take notice and really ponder the words of Jesus!
Relationship of the Beatitudes to the Fruit of the Spirit
Examining what was the relationship of the Beatitudes to the Fruit of the Spirit as noted in Galatians was the highlight of Question 1. Jesus fulfills the prophesies. Jeremiah noted that the law of God would be written on our hearts. There is no way that we, as Christians, can have the fruits of the Spirit, or follow the Beatitudes without God's Spirit within us. For example, Verse 10 of Matthew's beatitude says "Blessed or Happy are those who are persecuted for righteous sake....' Who without the spirit of God could be blessed or happy in such a situation. One must rely on the Comforter that Jesus promised to realize this. The fruits of the Spirit and the blessing or happiness spoken of in the Beatitudes are only possible through the gift of the Comforter promised by and given to all the believe!!
