In Isaiah 6, the prophet Isaiah experiences a profound vision of God seated on a high throne, surrounded by seraphim who proclaim His holiness. Overwhelmed by his unworthiness, Isaiah fears for his life, yet one of the seraphim touches his lips with a burning coal, declaring his sins forgiven, upon which God commissions Isaiah to deliver a message to his spiritually wayward nation. This episode provides a fitting introduction to this Network, seeking to recover a biblical, theological, and missiological vision of the holiness of God for church life and leadership today.
