Everyone of importance in the Bible practiced fasting: Moses, David, Elijah, Esther, Daniel, Anna, Paul, Jesus, just to name a few. When Jesus taught on fasting, He would say “When you fast” not “If you fast”. He assumed that we would fast. We were created with fasting, think about it, if you sleep 8 hours a day, then you are sleeping 1/3 of your life. If you live, say, 75 years, that’s 25 years asleep, or 9,125 days. When you sleep, you are fasting, that’s why morning meal is called breakfast – it's when you break your fast.
BENEFITS OF FASTING:
1. Helps us overcome the calamities of life.
Fasting is the Biblical way to humble ourselves (Psalm 35:13; 69:10). Esther fasted when faced with danger (Esther 4:16). Ezra fasted for protection (Ezra 8:21-28). Jehoshaphat fasted in the time of the invasion of the confederate armies of Canaanites and Syrians (2 Chronicles 20:3).
2. Renews our connection with God.
Jesus said that His disciples will fast when He is gone (Mark 2:20). When we fast, we get our hunger back for the presence of God.
3. Empowers us to fulfill God’s calling in our life.
Most of the people in the OT fasted in a crisis; Jesus fasted for His calling. We should not fast only during problems, but also for our purpose. Anna was fasting for the coming of the redemption of Israel. (Luke 2:37).
4. Defeats the devil.
Once, the disciples of Jesus could not cast out a demon. Jesus said, This kind does not leave, but by prayer and fasting (Matthew 17:21). Fasting helps to break the bonds of wickedness, undo heavy burdens, and empower us to break every yoke (Isaiah 58:6).
1. Full Fast.
Drink only liquids (you establish the number of days)
2. Partial Fast.
A partial fast is from 6:00 am to 3:00 pm or from sunup to sundown. You can select from three types of fasting: Full Fast, Daniel Fast or give up at least one item of food. (Chocolate)
3. The Daniel Fast.
Eat no meat, no sweets, and no bread. Drink water and juice. Eat fruits and vegetables.
HOW TO BEGIN:
1. Start With a Clear Goal.
Be specific. Why are you fasting? Do you need direction, healing, restoration of your marriage or family issues? Are you facing financial difficulties? Ask the Holy Spirit for guidance.
2. Preparing Spiritually.
Confess your sins to God. Ask the Holy Spirit to reveal areas of weakness. Forgive all who have offended you and ask forgiveness from those you may have offended. Surrender your life fully to Jesus Christ and reject the worldly desires that try to hinder you (Romans 12:1-2).
3. Deciding What to Fast.
The type of fasting you choose is up to you. You could go on a full fast in which you only drink liquids, or you may desire to fast like Daniel, who abstained from sweets and meats, and the only liquid he drank was water. Remember to replace that time with prayer and Bible study.
4. Deciding How Long.
You may fast as long as you like. Most can easily fast from one to three days, but you may feel the grace to go longer, even as much as 21 to 40 days. Use wisdom and pray for guidance. Beginners are advised to start slow.
5. What to Expect.
When you fast, your body detoxifies and eliminates toxins from your system. This can cause mild discomfort such as headaches and irritability during withdrawal from caffeine and sugars. And naturally, you will have hunger pains. Limit your activity and exercise moderately. Take time to rest. Fasting brings about miraculous results. You are following Jesus’ example when you fast. Spend time listening to praise and worship. Pray as often as you can throughout the day. Get away from the normal distractions as much as possible and keep your heart and mind set on seeking God’s face.
6. How to End.
Don’t overeat when the time comes to end your fast. Begin eating solid food gradually; eat small portions or snacks.
