This lecture examines Chapter 2 of the Westminster Confession of Faith, focusing on the doctrine of God and the Holy Trinity. It begins by establishing the oneness of God through the Shema in Mark 12, distinguishing the one living and true God from the polytheistic traditions of the world. This lecture explores God's attributes, emphasizing His immutability, infinity, and self-sufficiency, which provide a foundation for assurance and worship. The sermon contrasts God's unchanging nature with human fickleness, highlighting that His love and justice are not driven by passing emotions but by His eternal character. Finally, it addresses the Trinity, affirming that the Father, Son, and Holy Spirit are one God in three persons, offering believers access to the fullness of divine love and presence.
