In the movie, a penguin named Mumble follows his curiosity to find what's "out there." Swept up by his passion he almost dies and is placed in a position that allows him influence. In this position he does what comes naturally to him. He is reminded of his gift by a small child. And so he starts dancing!
He leads the way for his tribe and his guides are his sense and what was already given to him (his God-given giftings).
In the end, being true to his gift and the journey this took him on, saved his tribe.
This is similar to how we follow God and lead others along the way. Not a lot of certainty. Not a lot of proof. Only what we've been given and a compass for the next step. Only the voice of the one that whispers in the wilderness.
