“So then, King Agrippa, I was not disobedient to the vision from heaven.” (Acts 26:19)
“If I want to do anything for God, I see that it is necessary for me to get the knowledge of God. I cannot work on my own; I must get the vision of God (a heavenly vision). It must be a divine revelation of the Son of God. It must be that.
