If you really wish to follow Christ, if you want your love for him to grow and last, then you must be faithful to prayer. It is the key to the vitality of your life in Christ. Without prayer, your faith and love will die. If you are constant in daily prayer and in the Sunday celebration of Mass, your love for Jesus will increase. And your heart will know deep joy and peace, such as the world could never give.
