Lent, in Christian tradition, is the period of the liturgical year leading up to Easter. The traditional purpose of Lent is the preparation of the believer — through prayer, penitence, alms giving and self-denial — for the annual commemoration during Holy Week of the Death and Resurrection of Jesus, which recalls the events linked to the Passion of Christ and culminates in Easter, the celebration of the Resurrection of Jesus Christ.

So for my family, tomorrow marks the first day of Lent.
This year along with a friend, I am making a Jesus Tree. This is basically a felt banner of a tree with 47 different felt ornaments. Then for each day of lent you find the correct ornament/symbol and read the correlating verse of scripture. The intent is to give your children (although I may learn something myself) a visual and hands on way to learn about Jesus' life.
The purpose of Lent is to be a season of fasting, self-denial, Christian growth, penitence, conversion, and simplicity. Lent, 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.
