"Blessed are the poor in spirit, for theirs is the kingdom of heaven." Matthew 5:3
To be poor in spirit is to have a humble opinion of ourselves; to be sensible that we are sinners, and have no righteousness of our own; to be willing to be saved only by the rich grace and mercy of God; to be willing to be where God places us, to bear what He lays on us, to go where He bids us, and to die when He commands; to be willing to be in His hands, and to feel that we deserve no favor from Him. It is opposed to pride, and vanity, and ambition. Such are happy. -Albert Barnes
