Excerpts from Joy Haney’s book, “When Ye Fast”:
Paul instructed the early church to give themselves to fasting and prayer for a time (I Corinthians 7:5). If they needed, we need it. It is like an investment. Every time you pray and fast for a certain amount of time you are gaining ground. You are investing in a powerful kingdom-the kingdom of God. You are building yourself up in the power of the Spirit. It is important to be consistent for there will be times when you need to draw on that power.
The fire of His spirit always burns out dross and sets the soul aflame. When you fast in a way that is pleasing to God, your heart throb will be, “He must increase, but I must decrease.”
Your mind will constantly be inspired. Your faith level will increase and a new relationship will develop between you and the Lord Jesus Christ. It is the glory level. For as you decrease, He increases and you see His glory and His holiness.
