The work of evangelization depends on individuals as well as groups of people who will regularly commit to praying.
In The Joy of the Gospel, Pope Francis tells us: "The great men and women of God were great intercessors. Intercession is like a 'leaven' in the heart of the Trinity. It is a way of penetrating the Father's heart and discovering new dimensions, which can shed light on concrete situations and change them. We can say that God's heart is touched by intercession, yet in reality, He is always there first. What our intercession achieves is that his power, his love, and his faithfulness are shown ever more clearly in the midst of his people (The Joy of the Gospel, #283)."
We are all certainly in need of experiencing God's "power, his love, and his faithfulness" in clearly apparent ways in our parishes and in our daily lives. The call to prayer, however, can be one that fades over time, and soon we find that we are less fervent in taking time to intercede.
This is an invitation and a request to join in a "corporate" effort to intercede that we may experience the Lord's transformative power our lives, the lives of our parishes and in our entire church, both our diocesan church and the church universal.
