The Bishop of Bangor, the Rt Rev Andrew John, urged residents of Machynlleth to stick together "for April".
"This is not the end. It is a journey we must take together, fighting the fears, the anger and despair. We want April home," he said.
The Machynlleth community came together in prayer in an emotionally charged service in honour of missing April Jones.
Mark Bridger has been charged with the abduction and murder of missing 5-year-old April Jones.
