In one of his podcasts Dr. Jim Wilder, a neurotheologian said the following related to family: “The smallest group identity is two. And so, marriage is the ultimate expression of the most difficult group identity to form. Because is a mutual shared identity by two people who are about as different as they come, which is made to function in all conditions, 24 hours a day for the rest of your life span. And in it, people are mutually cared for and both people are satisfied. And they are able to take care of a wide variety of problems and all (both) will be glad to return to joy. That is the ultimate test of the hardest identity group to form.”
