Lent is fundamentally a Christian thing, a preparation of the heart and spirit for the solemn event of the crucifixion and resurrection of Jesus. It's a season of prayer, repentance, and self denial.
A lot of Christians fast or give up something for the Lenten season. I have friends that pick something they like and they fast from it. It is difficult and that’s the point.
You don't have to give something up! Here are some other ideas:1. Add prayer - check out 40 prayers in 40 days2. Read a devotional daily.3. Go meatless.4. Light candles.
