So let all who are devoted to You speak honestly to You now, while You are still listening. For then when the floods come, surely the rushing water will not even reach them. (Ps 32:6, The Voice)

This past Sunday a group of tourists exploring a glacial lake in Iceland was forced to run to safety after chunks of ice broke off a nearby glacier, spurring a massive wave.  Though they were at a safe distance, they soon discover the power of water as some escaped by the skin of their teeth.

David here is talking about prayer, specifically a prayer of confession.  He doesn’t want to be in a place where the tsunami of evil and sin will wash over him.  He knew that a flood has the power to destroy, knock down, and wash away.  Those tourists knew that the pending wave would have the power to drag them out to sea.  They needed to find higher ground, and find it quick.
