Repentance: what is it, why do it?

If you aren't used to Christianity and its lingo, you may have heard the word "repent" a couple times, and maybe you have a slight idea of what it means. If you are, you know that its one of the most common words in the faith, and you may or may not understand its incredible significance in becoming a follower of Jesus Christ, and even AS a follower throughout your life.
Regardless, you probably use this word more than you think you do,  just in a different form; the definition of repent is literally to "change" or "turn" from one thing to another.
Today, Zach and Michael talk about what this word means and how it changes the lives of those who take part in it.
