The doctrine of the Trinity is a distinctive mark of Christianity. Though there are “triads” (a set of 3) of divinities in many of the world’s religions and philosophies, none of these carries any similarities to the Christian teaching concerning the Trinity.
It must be understood, however, that it is not possible to “prove” the Trinity from the standpoint of human reason. The Trinitarian nature of God comes to humans by divine revelation.
It is interwoven throughout the Old and New Testaments. Therefore, the Bible presents God as a rational Spirit being who is unlimited in His characteristics of love, holiness, wisdom, peace, majesty, justice, truth, and goodness. It also presents Him as one who exists outwardly in three persons yet is still one in substance and in purpose.
Our text for today is 1 John 5:7, “For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one.”
It is very simple to state the two main points of our lesson:
First, there is one God.
Second, the one God exists as three persons.
Let’s begin by examining the Christian belief that: There is one God.
In the Old Testament God is revealed in the Shema. The “Shema” is the recital of Deuteronomy 6:4-5. Every service in every Jewish synagogue was opened by the people reciting these two verses. This is what they would say publicly, “Hear, O Israel: The LORD our God is one LORD: And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.”
God was also revealed in the Ten Commandments. The very first commandment is, “Thou shalt have no other gods before me” (Exod. 20:3).
The prophets of the Old Testament also revealed God. He is revealed in every one of the prophetic books. For example, the prophet Isaiah wrote, “I am the Lord, and there is no other; There is no God besides Me. I will gird you, though you have not known Me, That they may know from the rising of the sun to its setting that there is none besides Me. I am the Lord, and there is no other.” (Is. 45:5-6)
In the New Testament God is revealed in the words of Jesus. In John chapter 10 Jesus said, “I and My Father are one” (Jn.10:30). It can’t be made any more understandable than that; they are one in their fundamental nature, and they are equal in power and glory.
James wrote in his epistle, “You believe that there is one God. You do well. Even the demons believe—and tremble!” (James 2:19). It’s not enough to just believe that God exists, for that doesn’t even distinguish a person from Satan’s demons: but we must give ourselves to God as the Gospel directs, and love Him, and delight ourselves in Him, and serve Him, which the demons will not do, and cannot do.
