No matter what noble status a believer reaches, he will always be in need of Allah and in need of worshipping Him. He will still have to ask of Allah and he will still need to seek refuge in Allah. This was the way of the Prophets and Messengers. They always had hope in Allah. Yet, they also had a fear of Allah, even though they were from Allah's most exclusive awliya (friend). The Prophet (peace and blessings of Allah be upon him) himself said:
"By Allah, although I am the Messenger of Allah, I do not know what He will do with me." [Bukhari]
If anyone believes that he has reached a level wherein he is no longer in need of Allah, beseeching Him and worshipping Him, he has become deluded. He will then be one of the enemies of Allah instead of one of His awliya. Indeed, as a person comes closer and closer to Allah, his reliance upon Allah, his understanding of his need for Allah and his worship of Him becomes even greater. Those are some of the signs that he is getting closer to Allah and is truly one of His awliya.
