In John 11 Jesus arrived at Bethany after Lazarus had died. Martha and Mary both approached Jesus with exactly the same words, “If you had been here my brother would not have died.” Jesus did not reply with identical statements. He gave Martha practical hope, but Mary emotional empathy. Jesus knew the people he was caring for and treated them as individuals.
It would be profoundly ineffective to admonish the fainthearted, help the idle, or to encourage the weak. The fainthearted need care not rebuke. The idle need a change of perspective, not help to carry on as they are. The weak need practical help, not words.
