“Poor in spirit” is paramount to spirituality, because HUMILITY disposes a Catholic to live the Faith and the experiences increase spirituality. The Holy Spirit pours His Gifts over the lowly, but the arrogant may shun the Faith and deem the faithful dull, ignominious and pathetic.
“At that moment Jesus said: ‘My Father, Lord of heaven and earth, I am grateful that you hid all this from wise and educated people and showed it to ordinary people. Yes, Father, that is what pleased you.'” (Matthew 11:25,26)
The arrogant seeks pleasure and wealth, though life is temporary, fragile and transient, whereas the faithful seeks Grace, spirituality and God’s Kingdom. The proud can hardly tolerate Suffering, and often disdains the spiritual joy and peace of the lowly.
The humble live in this world, but is not of this world!
“Blessed are the poor in spirit, for theirs is the kingdom of heaven.” (Matthew 5:3)
