Much can be learned from those who have looked death in the face and yet remained true to the Lamb of God who takes away the sins of the world. Polycarp was such a man who learned from the great apostle John. Even under the threat of death, he remained true to his beloved bridegroom, Jesus Christ, who is blessed forever, amen! Even today, some 2000 years later, we have his own words and are able to learn from his wisdom. May you be blessed as you read this book. Amen.

    While Christians often struggle to find the right words to describe the union of Father, Son, and Spirit, the Bible gives clarity concerning the triune God's activity in nature (creation), grace (redemption), and glory (reward). In the second installment of the Short Studies in Systematic Theology series, theologian Scott Swain examines the Trinity, presenting its biblical foundations, systematic-theological structure, and practical relevance for the church today.
