In this blog series, we continue our walk through Wayne Grudem's Systematic Theology and we find ourselves in the deepest of doctrines...the Trinity.
To begin, I think it is important to recognize that the term “Trinity” is not in the Bible. This, however, does not mean that the Trinity is not in the Bible. The teaching of the Triune God is found as early as the first chapter of Genesis; in fact, the first verse. “In the beginning, God created the heavens and the earth.” (Genesis 1:1). The word for God in Hebrew is Elohim. Elohim is plural, not singular.
If we keep reading to Genesis 1:26 we see Elohim say, “Let us make man in our image, after our likeness.” If we stopped reading the Bible in Genesis we would believe that God is not one, but more than one. How many, we would not know.
However, if we continue to read the Bible we would also encounter passages such as Deuteronomy 6:4, “Hear, O Israel: The LORD our God, the LORD is one.” One means one. Likewise, in Isaiah 45:5, God says, “I am the LORD, and there is no other, besides me there is no God.” The oneness of God runs throughout the Old Testament and is confirmed in the New Testament. Romans 3:10 says, “God is one.”
In fact, this is one reason that the ruling class during the times of Jesus, wanted to kill Him, because He made himself equal with God. As they read the Scriptures (which only included the Old Testament at that time) they saw God as singular. “This was why the Jews were seeking all the more to kill him, because not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.” (John 5:18)
So as you read the Whole Counsel of God with a desire to make all text work, we see God describing Himself as one, and describing Himself as more than one. The way Grudem breaks down the Bible’s teaching is the following: 1) God is three persons, 2) Each person is fully God, and 3) There is one God.
Trying to wrap our heads around this concept is one of the most difficult tasks known to man, and I would argue that it is impossible to fully understand. And this is ok. We should embrace what He has revealed to us, and we should be glad that our God is one that beyond our comprehension. We should join in David when he expresses, “Such knowledge is too wonderful for me; it is high; I cannot attain it.”
It should also cause us to recognize that our God is relational at His core. This relationship within Himself is so pure and so perfect that it is one. This is the relationship that He calls us into, not one that is superficial, but one that is intimate, one that is abiding. And as the Trinity is eternally secure within itself, those who enter into this union through faith in Christ, by the power of the Spirit, for the Glory of God, are eternally secure as well
