There are traditionally 40 days in Lent; these are marked by fasting, both from foods and festivities, and by other acts of penance. The three traditional practices to be taken up with renewed vigor during Lent are prayer (justice towards God), fasting (justice towards self), and almsgiving (justice towards neighbors).
Lent, which comes from the Teutonic (Germanic) word for springtime, can be viewed as a spiritual spring cleaning: a time for taking spiritual inventory and then cleaning out those things which hinder our corporate and personal relationships with Jesus Christ and our service to him.
In addition, some believers add a regular spiritual discipline, to bring them closer to God, such as reading a Lenten daily devotional.
