The primary aim of fasting is to make us conscious of our dependence upon God. If practiced seriously, the Lenten abstinence from food – particularly in the opening days – involves a considerable measure of real hunger, and also a feeling of tiredness and physical exhaustion. The purpose of this is to lead us in turn to a sense of inward brokenness and contrition; to bring us, that is, to the point where we appreciate the full force of Christ’s statement, ‘Without Me you can do nothing’ (John 15: 5). If we always take our fill of food and drink, we easily grow over-confident in our own abilities, acquiring a false sense of autonomy and self-sufficiency. The observance of a physical fast undermines this sinful complacency. Stripping from us the specious assurance of the Pharisee – who fasted, it is true, but not in the right spirit – Lenten abstinence gives us the saving self dissatisfaction of the Publican (Luke I 8: 10-1 3). Such is the function of the hunger and the tiredness: to make us ‘poor in spirit’, aware of our helplessness and of our dependence on God’s aid.
