Yes.
A human needs someone to show him how to talk, speak, eat , live... A group of men, needs one to lead. And humans are social, we long for one another... is it not?
Many aspects of deen, needs someone to guide us. Some aspects of Imaan is strengthened, by community. We need examples. The mind always has doubts. We need someone to correct our wrong understandings. We need some one to give us feedback, to tell us whether we understood what we read in Quran and Sunnah correctly. A single person can get lost in his own world, even when he has the books of Sunnah, Quran, the evil Shaytaan is always conspiring... We need some one to talk to, when we are low, to speak our hearts out..
Thats where the righteous ones help us. A righteous person is closer to Almighty. The righteous knows to correct our wrongs in a good way, and appreciate our good deeds, without praising us beyond limits, thereby encouraging us in our journey on the right path. The best in the righteous community is worthy of being an Imaam, a leader, by his actions powered by his knowledge.
