To be the great in the kingdom of God, we must humble ourselves  -  Matthew 18:4

Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.

Notice the contrast to the world’s thinking – if we desire to be great, we must be humble. The standards and values in the kingdom of God are exactly opposite of those in the world. Our whole mode of thinking must be reversed, we must think Christ’s thoughts, so that we can think as He does.
