“All too frequently we take a different view of our trials and temptations. We tend to see them as isolated nightmares. God, however, sees them from a different perspective. They are important and connected punctuation marks in the biography of grace He is writing in our lives. They give formation, direction, and character to our lives. They are all part of the tapestry He is weaving in history. He uses them to build up our strength and to prepare us to surmount greater obstacles, perhaps fiercer temptations.”
― Lloyd John Ogilvie, The Preacher's Commentary - Vol. 21: Daniel

“The clearest description of second-century worship, however, comes from the account of Justin Martyr in his First Apology – an account we will turn to again below.
