Jesus fasts for forty days

Matthew 4:1-11

Fasting. In this text we see Jesus spending forty days fasting. Now I have to confess I have not personally spent a lot of my time fasting. My church has encouraged giving up something for Lent (the 40 days before Easter) and I have taken part of that. But fasting from food has not really been a part of spiritual life or journey. A few people in my congregation have said a couple things that have challenged me in this area.
So I began to ask why hasn't fasting been part of my life. The sense that I getting right now is that I think fasting is a waste of time. Why fast from food? God already hears my prayers, fasting isn't going improve that. Often fasting in the Old Testament was done to seek God's forgiveness. But because of Christ I am already forgiven.
One reason came to me why I should fast, fasting reminds me that I need God more than I need food. Do I really believe that?
There a some other reasons that I think fasting might actually be important. But I want to ask you: "Do you think fasting is something Christians should regularly do?"
