Keeping my fingers crossed

Meaning/Usage: Hoping for good luck

Explanation: In recent days, children would cross their fingers when they lie to avoid punishment for telling a lie. Another way this is used is to cross the fingers while making a promise to invalidate the promise. Christians used the gesture of crossing fingers to recognize one another in times of persecution. Therefore, people cross their fingers wishing for good luck from God.
