From Matthew 5:33-37, pastor Rob Lane helps us to understand the importance of making sure your yes is yes, and your no is no.
To be poor in spirit means to be empty before God. When a person is poor in spirit, there is an acknowledgment of one person's inadequacy before God. We should not be shocked that this is the first beatitude. If Jesus was about to preach into the hearts of his listeners, and now us, then we need to come to Jesus empty and needy.
