“Do not let your hearts be troubled” does not deny things that hurt the heart. That is why it is followed immediately by “believe in God, believe also in me.” An untroubled heart is not an act of strength or stone faced stoicism. It is as the apostle Paul writes to the Romans, a transformation brought about by the renewing of the mind. Even so “How can we know the way” and “Show us the Father” are legitimate questions and if disciples who saw “face to face” asked them then how much more should we “who see as through a mirror dimly” be allowed times of questioning. Jesus didn’t say it explicitly but I’m certain it was part of the plan that when he went off to design dwelling places he meant the disciples to wait together so that hearts might help each other beat as one. “Do not let” does not lead to troubles magically disappearing and long days and sleepless nights still wear down the body and the mind but believing the God of the cross has prepared a place of peace and comfort that comes with the Christ to hearts gathered as one is a sure and certain comfort for the afflicted and real rest for the weary.
