How long does a prayer have to be? Not long at all, according to Jesus. Only it needs to come from the heart. In Jesus’ book a long and eloquent prayer from a religious expert did not make the cut. But a cry from the heart – “God, be merciful to me, a sinner” – from someone out on the edge showed what prayer is all about. When we stop being full of ourselves and realise how much we need God, then we can truly pray.
