Where I live there is an endless supply of cactus as models! This particular variety is thornless, though, and those are rare. I have a friend who makes jelly from the prickly pear fruit every summer. She harvests from the variety that has thorns, though, and must use very heavy leather gloves to keep from getting stuck. I let her do the work and buy the jelly - no sore fingers for me!
2 Corinthians 12:7 To keep me from becoming conceited because of these surpassingly great revelations, there was given me a thorn in my flesh, a messenger of Satan, to torment me.
