Generally, the Christian leaders found difficulty to figure out the relevance of the doctrine of the Trinity in ministerial life. They just see the relevancy at little aspects, such as in the votum, baptismal service, and doxological song. But the rest, they dont understand how to apply the doctrine to the ministerial life. Probably, they understand the significance of the Trinity for believers, yet they dont know how to make the doctrine relevant to the vocational ministry.Therefore, the next question is how we should apply the doctrine in the ministerial life? In what way we should apply it?Through Seamand's Ministry in the Image of God, we may find the application of the doctrine. By arguing that the ministry we have entered is the ministry of Jesus Christ, to the Father, through the Holy Spirit, he then moves to the deeper characteristics of Trinitarian's life. There are seven characteristics: (1) the relational personhood which leads to an understanding of a person as a relational being as well; (2) joyful intimacy that brings us to an enjoyable ministry on the earth; (3) glad surrender that leads us into self-dedication to Christ; (4) complex simplicity which brings us into a realistic understanding ministry; (5) gracious self-acceptance that encourages us to be a person that understand other particularity; (6) mutual indwelling that can be exercised in several aspects, such as listening to others emphatically, intercessory prayer, participating in the team ministry, and marriage intimacy;(7) passionate mission which gives us strength and boldness to join in the missio Dei without fear.Above all, this book will give us profound thoughts, both in theology area and practical as well. Therefore, I recommend this book highly to be learnt carefully.
