The Rabbi from Nazareth didn't need a blackboard to teach eternal lessons. Chalk dust, blackboards, and bells. Desks, colored pencils, and paper. Teachers, students, and grades.
Teachers are the givers of such life-changing gifts.
Unique approach Jesus was called Rabbi, the teacher. Many sat at His feet to learn the wonders of life. Unlike our teachers today, Jesus had no blackboard as His backdrop, but He did have a hillside. Rocky, warm, and inviting. Jesus had no chalk to sketch His illustrations, but He did have nature.
