Q&A – Why Should We Fast?


Why should we fast? I know that Jesus fasted, but why is it important to us as Christians?


According to the Bible, fasting isn’t optional. In Matthew 6:16, Jesus says, “When you fast, do not put on a gloomy face as the hypocrites do, for they neglect their appearance so that they will be noticed by men when they are fasting. Truly I say to you, they have their reward in full.”

Jesus doesn’t say “if” you fast, Jesus says “when”. In this verse, Jesus is mostly talking to the Jewish people, but the apostle Paul talks about fasting, too. Paul is not talking to Jewish people, he’s talking to the rest of us.

…As servants of God we commend ourselves in every way: in great endurance; in troubles, hardships and distresses; in beatings, imprisonments and riots; in hard work, sleepless nights and hunger. – 2 Corinthians 6:3-5

Why fast?

We fast simply because when we give up something that we greatly desire, it causes us to fully rely on God for the strength we need to stay away from the thing we’re purging. You can’t give up something you love by using your strength alone — you must rely on God. Therefore, the principle of fasting is this: Turn to God constantly and rely on Him fully. Fasting doesn’t have to be about food either! It can be anything– fasting from TV, Facebook, anything that takes a lot of your time that isn’t spent on giving God the glory.

    I wanted to try fasting from food but my mother would not let me. It is really encouraging to hear that you do not have to fast from food but you can fast from other things too 🙂

    Wait! This is totally new to me. Is there like a special day to fast or do we do this anytime? And how do we fast? I never heard of us doing this before! Jews and Muslims , yes. But us? Wow.

    I will definitely try fasting from my computer since I am always on it. And since I love to eat, I will try to fast for at least half the day!

      according to the Bible and Jewish guidelines, one day is from sun up, to sun down. so if you can make it that long you’ll have completed one whole day 🙂

    I would fast with food but I would probably be yelled at for “trying to starve myself again”. I use Facebook to keep up with my family. What should I fast from?

      Facebook? or TV?

        I would suggest TV or secular music if you listen to that. Those are both good 🙂

    Fasting is hard,but it gets easier the more and more you do it becuase it makes you depend on God more. When you depend on God,the stronger you get. Most of all,it brings you SO much closer to God! Trust me,I know.

    I never believed in fasting, but now Im going to fast with my facebook! lol IM SO Addicted!

    We should fast because it helps us grow closer to God. When you give something up that’s important to you, it causes you to have to depend on God more.
