Can we demonstrate the doctrine of the Trinity from the Old Testament?

Summary

The sermon explores the theme of the Trinity, noting that while the Old Testament (Genesis, Ezekiel, Daniel, Isaiah, David) contains adumbrations and is not contrary to this doctrine, it is only fully revealed in the New Testament, as Augustine stated. The practical takeaway emphasizes the immediate acceptance of Jesus' divinity by New Testament Jewish believers, illustrating the need for sound hermeneutics and allowing Scripture to speak for itself rather than forcing interpretations.
