Before he heads to Jerusalem, Paul is wrapping up his ministry in Greece. But before he does, he gives them his final instruction, which is to stay united and be aware of the wolves that claim to be Christ, along with those who join the church and corrupt God's word. A wolf in sheep's clothing is more than a person - I believe a wolf can be a sport, it can be materialistic things, it can our jobs, but Christ says to deny ourselves and the things of the world so we can faithfully and fully devote our lives to him.
