I was told that thorns was placed by God to protect the delicate beautiful rose, that it’s beauty was to be admired and not touched. The Crown that was placed on Jesus’s head represented the never ending pain and suffering we endure mentally. So the crown of thorn was placed on Jesus’s head to protect. Jesus himself became like the delicate beautiful rose.
What most of us didn’t know exist is the thorns on Jesus’s heart. Just like the mind is very delicate like a rose, so is the heart. So symbolically the thorns was also placed on Jesus’s heart to protect that which is delicate and beautiful.
This was a great example of what Joseph with the rob of many colors who had the dream, told his brothers in Genesis 50:20 “As for you, you ment evil against me, but God meant it for good.” The soldiers thought the crown of thorns was to humiliate Jesus, but really they were didn’t know it was a spiritual protection for him.
