This book offers an in-depth exegetical and theological analysis of John 19:28-30, focusing on the profound paradox embedded in Jesus' cries of "I am thirsty" (Διψάω, Dipsaō) and "It is finished" (Τετέλεσται, Tetélestai). It meticulously examines the linguistic, historical, and socio-religious contexts of these phrases, exploring their intertextual connections within the Old and New Testaments and their theological implications, including Jesus as the fulfillment of prophecy, his obedience, and the significance of his death as a sovereign act leading to life and exaltation. Furthermore, the study delves into the dual nature of Christ, the tension between suffering and glory, and the eschatological dimensions of fulfillment, ultimately reflecting on how this paradox impacts Christian life, faith, and understanding of salvation, portraying the cross as the ultimate revelation of God's glory.
