Yesterday my family and I continued reading in our after-breakfast Bible reading time the section of Chapter 14, “God in Three Persons: The Trinity,” of Wayne Grudem’s Systematic Theology (Zondervan, 1994) which develops these statements about the Trinity: (1) God is three persons, (2) Each person is fully God, and (3) There is one God. We began reading what Grudem said about (2) yesterday and will finish reading it later today. Here I’ll consider some of the Biblical evidence that the Father and the Son are each fully God today and that the Holy Spirit is fully God tomorrow.
God the Father Is Fully God
The Bible opens with a record of God’s creating everything (Genesis 1) and closes with a vision of His sitting on a throne in the New Jerusalem (Revelation 21-22). In-between it portrays Him as sovereign Lord over all. Clearly He is fully God.
God the Son Is Fully God
I plan to consider the deity of Jesus Christ at length when my family and I read Chapter 26, “The Person of Christ,” of Grudem’s Systematic Theology, and so here I’ll give just a few passages that speak of Jesus Christ as fully God.
John 1:1-3 says, “In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made” (ESV; all Bible quotations are from the ESV). In the passage John observes that the Word, whom he identifies as Jesus Christ further on the chapter, was in the beginning, that he was with God, that he was God, and that rather than being created he shared in creating everything. Thus John not only speaks of Jesus Christ as fully God but also affirms that he always was fully God.
Other Bible passages that speak of Jesus Christ as fully God are:
– “Thomas answered him [Jesus], ‘My Lord and my God!'” (John 20:28).
– “Christ, who is God over all” (Romans 9:25).
– “In him [Christ Jesus] the whole fullness of deity dwells bodily” (Colossians 2:9).
– “He [the Son of God] is the exact imprint of his [God the Father’s] nature” (Hebrews 1:3).
– “But of the Son he [God] says, ‘Your throne, O God, is forever and ever'” (Hebrews 1:8, quoting from Psalm 45:6).
– “The glory of our great God and Savior Jesus Christ” (Titus 2:13).
– “The righteousness of our God and Savior Jesus Christ” (2 Peter 1:1).
