This is the ninth in a series of articles on the Trinity, excerpted from “What Every Christian Should Know About the Trinity,” available through Amazon and other booksellers.
While most arguments for the Trinity are grounded in the New Testament, God begins revealing His triune nature in the Old Testament. One hint at the plurality and unity of the Godhead may be found in several passages where God speaks.
For example, Genesis 1:26 reads, “Then God said, ‘Let us make man in our image, according to our likeness.’” Here, the verb “said” is singular, but the verb “let us” is plural, as are the possessive endings of the nouns “our image” and “our likeness.” Then, in the next verse we read, “So God created man in his own image; he created him in the image of God; he created them male and female” (v. 27).
Genesis 3:22-24 provides a similar clue: “The LORD God said, ‘Since the man has become like one of us, knowing good and evil, he must not reach out, take from the tree of life, eat, and live forever.’ So the LORD God sent him away from the garden of Eden to work the ground from which he was taken. He drove the man out …”
Other examples include:
Genesis 11:7, where the LORD says, “Come, let’s go down there and confuse their languages so that they will not understand one another’s speech.” Then, in verses 8 and 9, the LORD “scattered them” and “confused the language of the whole earth.”
Isaiah 6:8 – “Then I heard the voice of the Lord asking: Who should I send? Who will go for us?”
