About this listen
Prayer, Medicine, and Healing is an invitation to pray for the sick based on evidence from the Bible, church history, and the origins of the modern hospital. Tracing the history of healing from the Hebrew Bible and reviewing the healing ministry of Jesus and his disciples, Thomson K. Mathew examines church history (church fathers, reformers, holiness leaders, pentecostals, and charismatics Oral Roberts and Paul Yonggi Cho) and the history of hospitals to affirm both medicine and prayer.
He addresses skeptics, acknowledges fake healers, and presents strong evidence for all followers of Jesus to pray for the sick and expect healing. This inspiring audiobook is for those who administer healing, and the ones who seek healing and wholeness.

Why are you Lutheran? It's a valid question in this modern age of denominations, distinctions, and choices. Throw out all those notions you might have about what it means to be Lutheran. When it comes down to it, being Lutheran is really very simple. It's about following Jesus. We go where Jesus goes, we listen when Jesus speaks, we trust when Jesus promises. And we live because Jesus lives.

American Christianity teaches the centrality of the individual: my will, my experiences, my decision, my heart, my work, and my dedication. Yet we couldn't be more unaware that Christ and His saving and comforting work are being lost. Our minds and hearts are captivated in some way by those who often preach the Christian instead of Christ.
