Any difference between 'authenticate_user!', 'user_signed_in?', & 'if current_user'?

This may be a dumb question, but I'm finishing up this app using Devise & am just wondering, is there any significant difference between authenticate_user!, user_signed_in?, & if current_user? If so, then in what cases would I not use one or the other?

Thanks

Just reading the variable names you can see they are not the same thing. 

authenticate_user!

This is a method to check user authentication, i.e., check if login and password matches.

user_signed_in?

This method checks if a user is signed in on the application. If there are any data inside the session that tells the application a user is signed in.

current_user

This gets the user that is logged in the application.

Not sure what you mean by 'significant difference', all these do different things:

authenticate_user!  # Signs user in or redirect
user_signed_in?     # Checks whether there is a user signed in or not
current_user        # Current signed in user
