God is described with different words in the Bible, a few of which translate into English as LORD, Lord, the LORD almighty, God, God Almighty and so forth.
When reading these in different places in the Bible, you become aware that although God is “one” He is also “more than one”— God, Jesus, and the Holy Spirit. Together, they are referred to as “the Trinity” or “the Godhead.”
If they were the same, they would not appear separately as they do in Matthew 3:16,17.
If God, Jesus, and the Holy Spirit were the same, they would not have different names. The different names bestowed give them different powers for deliverance of human beings from their sins on the Judgement day.
Holy Spirit is the creator, the created and everything manifested in the Universe by the act of creator. God, the Father is the Protector of righteousness over evil. Jesus, his Son is the transformer. Jesus Christ brings in every human being the Christ consciousness to bring spiritual transformation in human beings to service every living and non living being with compassion, love and total devotion without any discrimination. The Christ consciousness removes human ignorance by getting rid of the desires, ignorance, greed, hate, envy and jealousy.
In spite of being different, they are “one.” (John 10:30) There is only one God, one Religion and one Truth with different names. God has many forms, attributes, names and reasons for coming down. Everything else is a manifestation of nature by the play of God.
The Trinity is one God existing in three Gods. Godhead takes the name and form based on the purpose. Holy spirit is the creator of the universe and everything manifested in the universe. Father has the responsibility of protecting good over evil. Son has the responsibility of bringing change in people by removing their ignorance about God. The following is what God’s Word says about the Trinity:
1) There is one God (Deuteronomy 6:4; 1 Corinthians 8:4; Galatians 3:20; 1 Timothy 2:5). God is the only Supreme Being in all existence, places, and time without any beginning or end. He is Holy (Rev. 4:8), Eternal (Isaiah 57:15), Omnipotent (Jer. 32:17,27), Omnipresent (Psalm 119:7-12), Omniscient (1 John 3:20), etc.
2) The Trinity consists of three Gods (Genesis 1:1, 26; 3:22; 11:7; Isaiah 6:8, 48:16, 61:1; Matthew 3:16-17, 28:19; 2 Corinthians 13:14).
In Isaiah 48:16 and 61:1, the Son is speaking while making reference to the Father and the Holy Spirit. Compare Isaiah 61:1 to Luke 4:14-19 to see that it is the Son speaking. Matthew 3:16-17 describes the event of Jesus' baptism. Seen in this passage is God the Holy Spirit descending on God the Son while God the Father proclaims His pleasure in the Son. Matthew 28:19 and 2 Corinthians 13:14 are examples of three distinct persons in the Trinity.
3) The members of the Trinity are distinguished one from another in various passages. In the Old Testament, “LORD” is distinguished from “Lord” (Genesis 19:24; Hosea 1:4). The LORD has a Son (Psalm 2:7, 12; Proverbs 30:2-4). The Spirit is distinguished from the “LORD” (Numbers 27:18) and from “God” (Psalm 51:10-12). God the Son is distinguished from God the Father (Psalm 45:6-7; Hebrews 1:8-9).
In the New Testament, Jesus speaks to the Father about sending a Helper, the Holy Spirit (John 14:16-17). This shows that Jesus did not consider Himself to be the Father or the Holy Spirit. Consider also all the other times in the Gospels where Jesus speaks to the Father. Was He speaking to Himself? No. He spoke to another person in the Trinity—the Father.
4) Each member of the Trinity is God. The Father is God (John 6:27; Romans 1:7; 1 Peter 1:2). The Son is God (John 1:1, 14; Romans 9:5; Colossians 2:9; Hebrews 1:8; 1 John 5:20). The Holy Spirit is God (Acts 5:3-4; 1 Corinthians 3:16).
5) The individual members of the Trinity have different tasks. The Father is the ultimate source or cause of the universe (1 Corinthians 8:6; Revelation 4:11); divine revelation (Revelation 1:1); salvation (John 3:16-17); and Jesus' human works (John 5:17, 14:10). The Father initiates all of these things.
The Holy Spirit is the means by whom the Father does the following works: creation and maintenance of the universe (Genesis 1:2; Job 26:13; Psalm 104:30); divine revelation (John 16:12-15; Ephesians 3:5; 2 Peter 1:21); salvation (John 3:6; Titus 3:5; 1 Peter 1:2); and Jesus' works (Isaiah 61:1; Acts 10:38). Thus the Father does all these things by the power of the Holy Spirit.
