Some of the ways people choose to fast.
The bible encourages us to fast but is not prescriptive about how we should do it nor indeed what it is. People fast in different ways and for different reasons. Here is one of the reasons I fast.
The only way an athlete wins gold is by disciplining and controlling their body. This is another reason why I fast.
Jesus was sometimes criticised for not fasting - or at least his disciples were. Why did he fast sometimes and not at other times? Because there are situations where justice has still to be done.
The spiritual discipline of fasting gives God the opportunity to teach, train and heal us. It is not a way of earning answers to prayer but of learning how to pray.
By working on appetites I can control, the Holy Spirit helps me deal with ones that would control me.
