  1. What It Means
    1. It is important that we have a correct understanding of the Godhead and of the Trinity.
      1. The first thing we must believe to be saved is that God is (Heb. 11:6), and that He is Triune.
      2. Among religions, the Christian faith is unique: our knowledge of God comes from God Himself.
    2. The early church laid the foundation for subsequent understanding and development of the Biblical doctrine of the Trinity.
    3. The true church maintains three persons in one being.
      1. In the one God there are three particular individuals, but not three Gods.
      2. They are distinguished by their names, which show their relationship to each other, their mode of action, and their effects.
  2. The teaching of the Trinity in the Bible.
    1. The teaching of the Trinity is revealed progressively in Scripture (Matt. 28:19; II Cor. 1:21,22; 13:14; I Peter 1:1,2).
    2. Though God began with a plural reference (Gen.1:26), He emphasized that He is the only God (Deut. 6:4; Isa. 44:6).
      1. Each of the three are identified in Scripture as God, and so the three together form the one being of God.
      2. These three persons constitute the one being who is God; agreeing in perfect harmony and working harmoniously.
  3. The importance of the teaching about the Trinity.
    1. The Trinity matters for creation (Ps. 33:6).
    2. The Trinity matters for life. God is life.
    3. The Trinity matters for relationships.
    4. Do you believe in God triune?
