What does it mean to be called? How does one discern his or her calling? There has been much discussion about these topics within the church, and perhaps much confusion as well. What if we could root the nature of the believer's calling and vocation from a missional perspective? This book seeks to understand how a deeper understanding of God's mission can help believers discern the work to which they are called and equip them for missional witness in and through their work. Importantly, rooting our understanding of vocation and calling in God's mission gives space for new emphases within the conversations related to faith and work, including theologically and contextually grounded emphases on creativity, vocational freedom, and vocational discernment, along with innovative educational models which can support believers as they navigate their work as participants in God's mission. When believers connect their gifts, talents, and creativity with God's work in and for the world in a way that is contextually relevant, it opens up opportunities for transformative witness for both believers and for the organizations they serve.
