Matthew 20:20-28 Greatness in the Kingdom of Heaven

Jesus says, "But whoever would be great among you must be your servant, and whoever would be first among you must be your slave, even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”

What is greatness in the kingdom of God? I. What is isn't. II. How hard it is. III. What it is.
