It’s like if God allows pain and suffering to happen in your marriage, like say Paul’s going to die from AIDS anyways and it’s going to be a short-lived marriage full of pain and disease. Likewise the Bible says that marriage’s not without difficulties and obstacles, whether if it’s serious incompatibility, arguments or the forthcoming death of a spouse due to AIDS.
I am doubtful of the prosperity gospel as there are rich and famous people who struggle with mental health problems, physical health problems like allergies to cats where it can be a life or death situation where if they come into contact with cats unless if there are hypoallergenic cats they’d risk coming into hives and stuff and other problems like divorce and drug addiction that it’s really not a walk in the park.
(Likewise King David committed adultery and had a child die, despite his wealth and power.)
Marriage’s not a walk in the park where God allows bad things to happen in your marriage to Paul, whether if it’s the loss of him due to AIDS or him not liking cats and dogs to the point where he even throws them away. There’s going to be a lot of suffering in your marriage to Paul where he even threatens to block animal websites because he doesn’t like animals at all.
Nonetheless, God is good where if your husband dies your suffering will die with him.
