I tell you, among those born of women, no one is greater than John; yet the least in the kingdom of God is greater than he (NAB) Luke 7:28
John was given a very great task, that of proclaiming the coming of the Lord, which he did whole heartedly. He became great for the kingdom of God by doing God's will. He let the people know of their errors to change their ways. By his preaching he reached the top, yet even with all that behind him the least in the kingdom would be greater than he. At that point in time the least in the kingdom happened to be Jesus, who was just starting out. Jesus teaches us how to become great for the kingdom of God. Are we up for the task that has been entrusted to us all.
