Bruce D. Perry and science journalist Maia Szalavitz explored the human need for love beginning at birth (I would go even further and assert that every child needs love beginning before birth). Perry and Szalavitz show how the human brain is hardwired for love, empathy, and a deep need to connect with others. Depriving a child of love can have detrimental life-long effects on them and others.
Indeed, I cannot think of anything more heartbreaking than being unloved, and knowing it.
and Church tell us so! Christ has been knocking at the door of your heart waiting for you to open it. He said, “Behold I stand at the door and knock, if anyone hears my voice and opens the door, [then] I will enter his house and dine with him and he with me.” (Revelation 3.19) In His immense and unfathomable love Christ has always been calling you. He wants to enter your life and dine with you. The New Jerome Biblical Commentary (2011) says that the reference to a meal may be the Lord’s Supper. The presence of Christ and his love is abundantly evident in the Blessed Sacrament.
The Catechism of the Catholic Church says,
chronically lonely can stand in unity; all sufferings of this present time are not worthy to be compared to the glory that will be revealed in us. We will yet bask in the warm embrace of Love Himself and finally know as we have always been known.
