Isn't a lie the most difficult sin to commit?

A lie is a great sin, but it can also help you out, too. Meaning, come on, people lie everyday to either keep them out of trouble, or telling ppl, that a certain person ain;t home if to protect one. But when you lie, and it depends on the kind of lie you make, it can lead to some dire consequences... But lying is an everyday part of our lives, whether to gain personal gain, or to help protect others...
