The New Testament states that one of God’s purposes in sending Christ to this world was to reveal Himself more fully to man (John 1:17-18). The study of the Holy Trinity is a glimpse into God’s divine nature as revealed to us more clearly in the New Testament, for without this fundamental precept there can be no deity of our Lord Jesus Christ, or of the Holy Spirit. Through the Trinity we see real unity in God the Father’s love, Jesus’ grace and intercession, and the Holy Spirit’s comfort and presence in us.


  1. Genesis 1:1 states, “In the beginning God created the heaven and the earth.” The Hebrew word for God here is the plural form, “Elohim.” Used together with the singular form of the word, “created,” we see the unity of the divine Godhead in the work of creation. Verse 2 of this chapter refers to “the Spirit of God,” completing the reference to the Trinity. What words in each of the following verses demonstrate the Trinity? See Genesis 1:26; 3:22; 11:7 and 1 John 5:7.
  2. What does the last part of 1 John 5:7 tell us about the Trinity?
  3. In the Matthew account of John’s baptism of Jesus, describe how each person of the Trinity was revealed.
  4. Why do you think the account of John’s water baptism of Jesus occurs in all of the four Gospels?
  5. John the Baptist spoke of Christ’s ministry as fulfilling and exceeding his own. What promise was given to those who believed in Christ regarding the third Person of the Trinity—the Holy Spirit? See Matthew 3:11 and Mark 1:8. What promise is given to people today in this respect? See Acts 2:38-39.
  6. What is the contribution of each person of the Godhead toward the salvation of mankind? See Romans 5:5- 6. For a clearer understanding of the work of the Holy Spirit, see John 16:8,13-14.
  7. In what attitude of prayer and worship should we come into the presence of the Triune God who extends to us His infinite authority and power? See Isaiah 55:6-7; 57:15 and Hebrews 13:15.
