Have you ever gotten down on your knees begging or crying out for God's mercy, even if you are not facing any crisis or in a jam? It is something most beneficial spiritually we should do as often as possible. Doing it shows that we are willing to submit to God, need his mercy, and want to be drawn close to him. This is imitating the humble tax collector who begged for God's mercy beating his breast and whom Jesus justified (Luke 18). Not ever having done so shows the lack of humility.
