This book explores the critical role of affability in contemporary outreach, aiming to bring this often-overlooked virtue into the spotlight. The author engages the writings of Pope Francis and selected saints expressing that affability is a virtue which impacts human relations for the good of the world, propelling evangelization efforts to the fullest level. The reason for its effectiveness is because friendly interactions influence the lives of both the giver and the receiver, which offers encouragement and produces joy. Evidence of this rests not only on the tenets of the Gospels and of the teachings of the Church but also on modern studies concerning the neuroscience of emotion and other areas of psychology.
