I have never found a problem with people from different religions praying together. What I have found is that people are just hungry for God, and be they Christian or Muslim we invite them to pray with us.
Mother TeresaWhere was Mother Teresa's Jesus? He was in the Bible, in the church, in her prayer, in the Eucharist, in her sisters, in the heart of everyone she met, and especially in the poorest of the poor and the lowest of the low. Jesus was in disguise in each one of them. Jesus was behind the foundation of her order. Jesus was behind all that she did.
Mother TeresaIf you try, you will find it impossible to do one great thing. You can only do many small things with great love.
Mother TeresaWe need silence to be alone with God, to speak to him, to listen to him, to ponder his words deep in our hearts. We need to be alone with God in silence to be renewed and transformed. Silence gives us a new outlook on life. In it we are filled with the energy of God himself that makes us do all things with joy.
