I am very happy about this. It makes me realize how much what we hand on to our kids is informal and, in a sense, unintentional. My kids appear to have notice, whether consciously or not, that the office is my favorite form of prayer and that my wife loves to pray it as well.
The daily prayer of a Christian should be biblical (esp. the Psalms) and ecclesial. I also believe in devotions, but the best of these (like the Rosary) is also biblical and ecclesial (strong ecclesiastical approbation, even if not the official prayer of the Church). Litanies fall in this category, and the Angelus. As I've mentioned before, I always take a Bible to Eucharist Adoration. Note: I don't think that Bible reading should be the focus of adoration, contemplation of the Face of Jesus should be, but the Bible can help us move into contemplation. The Word helps us see the Word.
Oh. I like to sing praise songs.
