The Verse that Trembles the Heart. Have you ever had one of those days? You know, the kind where everything just seems to go wrong? And, when everything goes wrong you just want it to stop. But then. God is the creator and sustainer of life. All things work together for Good for those who are called according to God’s purpose. We are all called according to do something. God has a purpose for all. So, why is it that we shy away from that to which God calls us?
