Lembersky's work is intensely spiritual in defiance to atheism endorsed by the Communists. His art is centered on the idea of a two-tiered reality, expressed in painting as a union between recognizable objects and hidden symbols shown “between the lines.” He frequently included religious symbols in his paintings. He was haunted by the memory of Holocaust. His 'Execution. Babi Yar' series (1944–52) are the earliest known artistic renderings of the Nazi massacres in Kiev. In his later work, he persistently brought back Holocaust symbols to his semi-abstract canvases. The themes of war and industrial labor—as alternating forces of destruction and reconstruction—appear again and again in his work. Yet, in contrast to the gravity of the content, Lembersky'S paintings appeal to his viewers with brilliant color, light and formal beauty. His art speaks to the universal experience evoking emotional response and delighting the eye.
