We used this chart to show our students why it is not possible to say that Jesus was for example "a great moral teacher" but He was not God. Jesus Himself claimed to be God. Either Jesus’ claims were false and he knew it (that would make Him a LIAR), or his claims were false and he didn’t know it (that would make Him a LUNATIC), or his claims were true and He is the LORD. But there is no room for believing that He was a great, but merely human, teacher.
