The Trinity

Title: What the Bible Says About the Trinity

Scripture Reading: 1 John 5:7

Text: For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one (1 John 5:7)

The doctrine of the Trinity is a distinctive mark of Christianity. Though there are “triads” 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.

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 14 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.

When Paul wrote his first letter to the believers in the Corinthian church he said, “Therefore concerning the eating of things offered to idols, we know that an idol is nothing in the world, and that there is no other God but one. For even if there are so-called gods, whether in heaven or on earth (as there are many gods and many lords), yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live” (1 Cor. 8:4-6).

He is described as the Father “of whom are all things.” We Christians are better informed than other religions, because we know that there is only one God, the source of life, the author of all things, the maker, preserver and governor of the whole world.

And in Acts He is described as the one in whom “we live, and move, and have our being” (Acts 17:28).

In Him we live, that is, ultimately it is God who provides for all our needs and we could not live unless He supplied the air, the water, the gravity, the sun, and everything that human life depends upon.

In Him we move; it is by God’s divine involvement that our thoughts run the course of a thousand subjects, and we could not move a hand, or a foot, or our tongue unless He moved them first.

In Him we have our being; not only because He gave us life, but we have it still because He continues to care for us and to be good to us.

Adam and Eve believed in one God, but their sin gave birth to polytheism, the worship of many gods, because in his guilt, man manufactured gods whom he could appease.
