Jesus doesn't give us these beatitudes so we can pat ourselves on the back. Because it's our nature. Like the nature of a scorpion is to sting. From BSF- the circumstances which bring some men to God's blessing are identical with those which cause others to curse God. Someone has said that we are either like a potato or an egg.
Boiling water hardens eggs and softens potatoes.
The very same circumstances result in opposite effects. If you are experiencing very humbling circumstances, it may well be that God is bringing you to the point of being 'poor in spirit,' and of being a true mourner who seeks the righteousness of God. Adversity brings some men to distrust self and to turn to God for eternal salvation. Then you must turn to Jesus Christ in faith. He died for sinners.
