We all say we have Iman (Faith). One might ask: what is Iman? the word Iman has the same roots as Amn (أمن) which means security or safety. To have faith (Iman) means what we believe from within us or from within our heart is going to give us safety and security. So when we say we believe in One God (Allah), we believe He is going to protect us. Hence He provides safety and security. when our believe is true and free from any forms of hypocrisy, then it will manifest itself on the outside. This is what the above quote says. The actions testify the faith within the heart. Furthermore, this is also what we understand from the Saying that the heart is like the king and the limbs are the subordinates. Whatever the king orders, the subordinates obey and follow. So if the king is corrupt, the entire body will be corrupt and there is no place in Jannah for what is corrupt. What we conclude is instead of focusing solely on the outward look, we need to focus more on our inside and try to purify our heart. The beauty within us is going to reflect to the outside. May Allah help us purify our hearts & shine our hearts with light of Iman & grant us entry into His Jannah.
