Matthew 5:3 says “Blessed are the poor in spirit, for theirs is the Kingdom of Heaven.” This almost indicates those poor in spirit will go to Heaven while I have always believed to go to Heaven you must accept Christ as your savior which would indicate one must have spirit.
This is the danger in taking a single verse and trying to build a doctrinal position with it.
In John 3:3 Jesus said only those who are born again will see the Kingdom. Therefore He couldn’t have meant all a person has to be is destitute of wealth, influence, position, or honor, which is what poor in spirit means.
He was saying that the poor in spirit are the people most likely to be receptive to the Gospel message because they don’t have as many ties to this world. It was a way of telling them not to lose heart because they had a better chance of inheriting eternity than most.
