Genesis 1:26-27, Then. God said, "let US make man in Our image, after Our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps over the earth." So, God created man in His own image, in the image of God He created him; male and female, He created them......... The MacArthur Study Bible states the very name of God Elohim, is a plural form of El. This is the first clear indication of the Trinity of God.
Genesis 11;7, "Come let Us go down and there confuse their language so that they may not understand one another's speech." So, The LORD dispersed them from there over the face of the earth, and they left off building the city........R.C. Sproul, The Reformation Study Bible states, "Some view these verses "As an indication of plurality within the divine unity, hinting at the later New Testament revelation of the one God, as Father, Son and Holy Spirit. We may not separate the three members of the Trinity, but we must distinguish between them."
Matthew 3:21-22, When all the people were baptized, it came to pass that Jesus was also baptized; and while He prayed, the heaven was opened. And the Holy Spirit descended like a dove upon Him, and a voice came from heaven which said, "You are My beloved Son, in You I am well pleased." ........ "All three persons of the Trinity are distinguishable in this verse." John MacArthur, The MacArthur Study Bible.
The book of Daniel does not contain a full revelation of the three persons of the Trinity.
However, the "Son of Man" in 7:13-14 is portrayed as having both a human and divine nature as the New Testament affirms about God the Son. Also, while Nebuchadnezzar
speaks from his polytheistic perspective, his speech in 4:5-6, states that in Daniel is "the
spirit of the holy gods," seems to reflect that Daniel was filled with God the Holy Spirit.
Daniel, Commentary, Andrew E. Steinman, p 31.
The word Trinity is not in the Bible but if you want to see a clear picture of the Trinity look at 2 Corinthians 13:14. "The grace of the LORD Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all." The Trinity is in the book of Genesis all the way through Revelation, over and over again. Look at the order here. It's the natural flow of salvation and sanctification in our lives. Once we receive the Lord Jesus Christ, we are able to engage in love with the Father. Because He is Holy, Holy, Holy, we can be in a relationship with the Father with His grace through Jesus Christ, and then communion with the Holy Spirit follows. Matt Geisinger. Sermon, March 19, 2023
