at times life can hit you hard , so if anyone's is going through a difficult time , God will bring you through it if you allow him, God knows the end from the beginning, and he sees the things we cant see. The fiery furnaces are there by Gods direct permission, it is misleading to imagine that we are developed in spite of our circumstances, we are developed because of them. its mastery in our circumstances that is needed , not mastery over them. God didn't deliver Shadrach, Meshach, and Abed-nego from the fiery furnace, he got in there with them and walked them through it.
