Why laugh? Don't you believe Jesus honors His Mother?
Mark 3:31-34 “31 Then Jesus mother and brothers arrived. Standing outside, they sent someone in to call him. 32 A crowd was sitting around him, and they told him, Your mother and brothers are outside looking for you.
33 Who are my mother and my brothers? he asked.
34 Then he looked at those seated in a circle around him and said, Here are my mother and my brothers! 35 Whoever does Gods will is my brother and sister and mother.
Jesus honored his mother (and since it’s best to take scripture in context his mother means his actual earthly mother, Mary) and his BROTHERS. Since they are mentioned in same context, I’d say they’re actual brothers.
Secondarily this scripture doesn’t really in any humanly way honor his mother and brothers.
