In this collection of writings from one of the most well-known theologians of the modern era, Packer strongly defends Trinitarian theology and the uniqueness of Jesus Christ against contemporary challenges. He calls for believers to be serious about the Holy Spirit, and his insights on this topic provide a template for applying theological beliefs to controversial issues within the church. Chapters include issues such as the universal and particular nature of God's love, the problem of universal aims and, as mentioned, the Holy Spirit.
