Yes, I have personally witnessed miracles as a result of the work of the divine spirit.
Individuals that perform righteously through spiritual principle produce miracles daily.
I once witnessed a stranger speak with someone who I discovered on a ledge at the top of a 5 story building. The distressed individual was about to jump to their death from the building. During the conversation, the distressed individual asked why they should get down from the ledge. The stranger told them that "God loved them and did not want them to commit suicide".
The distressed individual then asked for a sign that this was true. The stranger then fell to their knees and prayed loudly to God for a sign. The stranger continued to pray loudly and then asked that a single sunbeam be placed upon the face of the distressed individual. Like a perfectly framed scene from a movie, a large sunbeam quickly formed upon the distressed one. The praying stranger then asked God to warm the distressed individuals heart with tenderness and to ask the distressed to step down from the dangerous ledge. The distressed individual then walked off the ledge to safety. He was then hugged warmly by the stranger.
While police and medical personnel hurried to the top of the building, the stranger walked past me and said, God be with you always. He then slipped away from the scene.
When the medical personnel asked the individual what was wrong, he stated, "Nothing, I just met with God and now know that I am loved." The medical people then took the individual to the lower levels of the building where his family had gathered. The young man then informed his parents that he had seen a vision so spectacular that it had included his reason for being.
I never saw the stranger again even though I worked in that building for over 10 years.
