Why do we celebrate Lent?

Lent is celebrated to show our penance to God for all the sins we have committed. In lent, you fast, abstain, share, give, pray, and it is supposed to be a time of peace, meditation, and reflection. Every Lent, you are supposed to give up something that you most enjoy. Or you can start doing more things as a daily routine. For example, I am giving up swearing and junk food.
