"Blessed are the poor in spirit, for theirs is the kingdom of heaven." (Matt 5:3)
“Seek the Kingdom of God above all else, and live righteously, and he will give you everything you need." (Matt 6:33).
We are to seek the Kingdom of God above every other thing, and now Jesus is say the Kingdom of God is for those who are poor in spirit. This mean that if truly the Kingdom of God is ours then we are poor in spirit. But what does "poor in spirit" mean? The word poor there does not refer to lack of money or material wealth, and the word spirit there is definitely not referring to a spirit being.
"Poor" as used in this scripture refers to humility, emptiness, and lack of sufficiency in one's self. Yes, a man is considered poor when he finds no sufficiency in himself, he is not full of himself, but rather empty and in utter reliance on God. He leans heavily on God as he has nothing and can do nothing by himself. All that he has is God, he is utterly empty of himself. He finds himself always depending on God, for he does not know how to survive without God. Now, to understand the word "spirit" as used in that scripture we would look at another scripture.
"And be renewed in the spirit of your mind;" (Eph 4:23).
The word spirit here is also not referring to a spirit being, rather it means a spiritual construct. Some other translation puts it this way, "to be made new in the attitude of your minds;" Attitude is a disposition, a state, an arrangement, a construct. The spirit of your mind therefore means the disposition of your mind, how your mind has been constructed to think, its attitude, how it behaves. A proper interpretation of that would be, "the spiritual nature of your inner man".
"Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day." (2Cor 4:16).
Yes, the nature of your inner man, that person that you are inside needs to be renewed day by day as we are being conformed to the image of Christ. The person that you are inside determines how you think, how your mind behaves, and therefore what you do. Our spirits already has the nature of Christ, but our soul, our inner man, still needs to be conformed to that. We need to start expressing this divine nature, and as the scripture says, "out of the fullness of the heart the mouth speaks" (Matt 12:34).
We simply express who we are inside, the spiritual nature of our inner man. It is the nature of our inner man that needs to be constantly renewed, conforming to the nature of Christ. Therefore when Jesus said, "poor in spirit", he was referring to the spiritual nature of our inner man. He is saying that deep inside of us we must have this attitude of poverty, emptiness, humiliaty, and lack of sufficiency in ourselves. We must come to the end of ourselves and learn to only lean and depend on God for everything.
"Jesus gave them this answer: "Very truly I tell you, the Son can do nothing by himself;" (John 5:19).
The son can do nothing by himself, he has no sufficiency in himself, he is utterly empty. This is the attitude of a slave who owns nothing, even himself does not belong to him, he is the property of another. Therefore no matter how much is in his possession or how great is the estate that he overseas, he is poor, it does not belong to him, he owns nothing. Jesus is saying the Kingdom of God is for those who have this attitude, who are empty inside, who sincerely feels like they own nothing despite their fat pocket, the large figures in their bank account, the properties that is in their name, the number of talents, skills, abilities, qualifications and the greatness of the knowledge they have.
They see themselves as empty before God, always relying on Him rather than their money, knowledge, wisdom, skills, abilities, talents, understanding, qualification, status and power in the society. They may be rich in all these things, but they rely on God instead, they feel like God is their true riches, their true qualification, their true wisdom, knowledge, understanding, their true power, talent and ability.
He is their all in all, the one and only thing they truly have. When we come to this level of emptiness then we are comformed to the true citizens of the Kingdom of God, for this is how the citizens of the Kingdom should be, this is their true nature and we need to start walking in that nature if truly we believe that we are the citizens of the Kingdom of God.
