Are today's apostles neglecting the life of prayer? Overwhelmed by multiple urgent tasks and limited in number and quality, we, today's evangelizers, tend to speak much about God to others without having spoken enough to Him. A hectic evangelizing activity, rarely joyful, is emptying the apostolic life of meaning. Before they were sent out, the Twelve were Jesus' companions, sharing His lifestyle and the work for the Kingdom. Having carried out their mission, they returned to Him for a communal living. This means that prayer is not another activity to be added to their evangelizing activity. To be with Jesus is not a loss of time, it is the way to reach the goal of becoming His envoy and receiving His recompense. The ten ‘lectios’ contained in this book have been composed and prayed in order to introduce us to communal living with the Teacher and seeks to offer the motivation, and the way, so that one who knows he/she is sent by Jesus may take up the life of prayer as His first apostolic service.
