In John 11, I am certain that the name Lazarus had been cried forth multiple times by people who loved him dearly, but he never heard them because he was dead. He wasn't ignoring them, he was just dead. It didn't happen all at once and neither without prayers and pleas for divine intervention. It didn't happen because God didn't love Him or because his family and friends could have done more and didn't.
"Pastor, we just feel led to leave" is occasionally the explanation - most often there's not one. Then, with so many dwindling congregations looking for fresh meat, finding a new fellowship is easy - and with no questions asked. Of course sometimes God does lead us to new opportunities but we must be cautious because clever justifications for putting distance between ourselves and disappointment or responsibility is nothing new.
Christ desires to be our advocate "one called alongside" (I John 2:1-2). The context addresses our standing before God as guilty sinners with Christ standing beside us speaking on our behalf-- speaking as One who has satisfied (propitiation) His own wrath for our sin. Sounds like only a fool would refuse such essential and unwarranted grace.
