In this devotional, Pastor Jason Van Bemel delves into the profound mystery of the Trinity through the lens of the Heidelberg Catechism (Questions 24–25). By exploring key scriptural passages from Genesis to Revelation, he explains how God is uniquely one, yet reveals himself as three distinct persons: Father, Son, and Holy Spirit. From the plurality in the name Elohim to the baptism of Jesus and his divine claims in Revelation, this study offers a compelling look at the foundational doctrine of the triune God.
