How do we get more saintly laborers to the harvest?

Jesus tells us in Luke 10:1-2, that the harvest is plentiful, but the laborers are few. Simply put, Jesus calls many men to Holy Orders for example, but few respond to the call. I believe that in order to get more holy laborers to the harvest, a saintly clergy is required. You see, a saintly clergy will draw holy men and women to the different vocations (Holy Orders, Religious Life, Married Life, and Single Life) within in the Church, by providing holy spiritual direction. So in order for the clergy to be successful in providing holy spiritual direction, which will produce more holy laborers to the harvest, we must pray daily for the continued holiness of those who are in the Sacrament of Holy Orders. This prayer for the continued support of the clergy can be as simple as praying one Our Father during the day.  

Furthermore, please remember to pray daily for God to send more saintly laborers to Holy Orders, Religious Life, Married Life, and Single Life, and that people may answer positively to God’s call. In addition, please remember to pray daily for the continued holiness of those who have been laboring in Married Life, Single Life, and as religious brothers and sisters, and for the continued holiness of religious orders. These prayers can be as simple as praying one Hail Mary during the day.
