Give a man luck, and throw him into the sea.

The saying treats luck as enough to protect a person even when he is placed in grave peril. Its image makes good fortune seem stronger than the danger surrounding him.

It expresses the idea that exceptional good luck can carry someone through circumstances where success would otherwise appear unlikely. The emphasis is on fortune’s power, not on a reliable method for safety.

Use it to comment on someone who appears to escape a dangerous or difficult situation through remarkable good fortune rather than through an assured advantage.
