Book excerpt: Knowing God and His attributes, how He saves and answers prayer is foundational to all truth and eternal life. Section one deals with proper attitudes we bring to the Old Testament text, knowing it is God's self-revelation Section two points out passages where two Persons manifest divine attributes or are called God, Jehovah or Lord: and Who is the Angel of the Lord. Section three explains the texts where three Persons are called God, Jehovah or Creator. Here we see the lie of the Da Vinci Code as hundreds of years B.C. Jesus is called God. God's self-revelation in the Old Testament is proved by hundreds of fulfilled prophecies we enumerate. The appendices deal with: the eternal personality of the Spirit; How to pray with Trinitarian Resources; Biblical words and phrases twisted by sectarians; the Trinity in the New Testament and Divine Names given equally to Jehovah and Jesus.
