What is the purpose of fasting, and how do you do it? Andrew answers these questions and gives a general teaching on the subject. Fasting doesn’t change God, but it changes you. Fasting is a way to make you sensitive to the things of God. It is a powerful tool, and it is more than going without food. Fasting is supposed to put your spirit in charge and get your mind focused on the Lord so you can perceive what is already in you.
