Miserere mei, Deus, miserere mei: quoniam in te confidit animas me.
Have mercy on me, O God, have mercy on me for my soul trusteth in Thee.
Manual labor is good for the body, mind and soul.
This is the gift of Lent. The Church instructs us in prayer, fasting, and almsgiving in hopes that these means will draw us into the desert with our Lord, lending to a greater conversion of heart. With greater recourse to prayer, Holy Mother Church prays that we may hear the voice of God more clearly and drawer nearer to His heart. By fasting - both from food and other methods, such as refraining from stating one's opinion - the Church prays we may see that which we are attached to, and instead attach ourselves to God's Holy Will. Through almsgiving - either financial or giving of one's time or gifts - the Church calls us to go out of ourselves and focus on another, as Christ did nothing but give and give.
Let us, then, with all our hearts, ardently implore His mercy upon our souls and turn back toward Him Who loves us more than we could ever imagine. Let us take up our cross with Him and begin the 40 day journey from the desert to Mt. Calvary.
