The Treasury of Daily Prayer (from CPH in the ESV version of the Bible)
Pray Now (the iPhone app for The Treasury of Daily Prayer)
Martin Luther's thoughts about Psalm 119 and the spiritual formation themes of … Oratio, Meditatio and Tentatio (prayer, meditation on the Scriptures and the Daily Troubles of Life)
