Answer: While the word trinity is not found in the Bible, the concept of 3 divine entities in the Godhead is Biblical. We clearly see three distinct persons at the baptism of Jesus “And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him: And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased” (Matthew 3:16,17).
And Paul frequently referred to the three separate persons of the Godhead “The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all” (2 Corinthians 13:14). “How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?” (Hebrews 9:14).
Also, John in the book of Revelation speaks about the three persons of the Godhead “From the seven Spirits who are before His throne, and from Jesus Christ, the faithful witness, the firstborn from the dead, and the ruler over the kings of the earth. To Him who loved us and washed us from our sins in His own blood, and has made us kings and priests to His God and Father, to Him be glory and dominion forever and ever” (Revelation 1:4–6 NKJV).
Jehovah’s witnesses do not believe that Jesus was God in the flesh. They believe Jesus was merely a created being. Here are some Bible verses that state that Jesus Christ is, indeed, God in the flesh:
“Christ came, who is over all, God blessed for ever. Amen” (Romans 9:5).
“Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God” (John 20:27,28).
“I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty” (Revelation 1:8).
“But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting” (Micah 5:2).
“Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high” (Hebrews 1:3).
“In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God.All things were made by him; and without him was not any thing made that was made” (John 1:1-3).
“It pleased the Father that in him should all fullness dwell” (Colossians 1:19).
“And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever” (Revelation 5:13).
“And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life” (1 John 5:20).
“For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace” (Isaiah 9:6).
It is clear that the Bible teaches the concept of trinity and that Jesus is indeed God the Son.
