More than a good teacher
Jesus didn't leave "good teacher" on the table as an option. He claimed to be God in the flesh - and then backed it up.
A lot of people are comfortable with Jesus the wise teacher. But Jesus never presented Himself that way. He said things no mere teacher could say: "I and my Father are one" (John 10:30). He forgave sins - something only God can do (Mark 2:5-7). He accepted worship without correcting anyone (John 20:28).
As the old argument goes: a man who says the things Jesus said is either lying, insane, or actually Lord. What He doesn't leave room for is "just a nice man with good ideas."
