Engraver Graham Short, 67, spent close to 320 hours carving the Bible passage, in lettering half the size of a red blood cell.
The engraving reads: "It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
Graham, from Birmingham, takes tablets to lower his heart rate and even injects botox into his eye to relax his body enough to do his minute work using a microscope, the 'Daily Star' reported.
Graham's exhibition at the Art House Gallery in Kelso, Roxburghshire, sold out in two minutes.
"Graham's work is absolutely fantastic. He does a brilliant job. He has the patience and skill to slow his body right down and create his mini masterpieces," said Gallery boss Tony Huggins-Haigh.
