It doesn't do any good for me to enter a conversation if I'm so tongue-tied that I cannot express, clearly and correctly, what I believe and why. That's just one more reason for Lent.
Fasting is not a way to seem more spiritual than others, it is to be done in a spirit of humility and joy. Lent/ fasting should not be a duty, but rather a celebration of God’s goodness and mercy to his children.
