Karen Swayne from Number One wrote, "This isn't one of the best tracks, but there's a warmth and humanity to it that means all but the hardest hearted will forgive him (for) crooning trite platitudes like 'problems have solutions/trust and I will show.' Some people might even believe him. And why not." Charts
