Relationships are the building blocks of humanity, writes Dudley Rutherford, author of God Has an App for That, and senior pastor of the 10,000-member Shepherd of the Hills Church in Los Angeles. Relationships, he says, can elicit overwhelming joy, such as the special bond between parent and child or the enduring love between a husband and wife.  However, the breakdown of relationships – seen across the ages and across the world – can cause unbearable devastation. Couples divorce, family members become estranged, siblings fight, and longtime friendships dissolve bitterly.
