The Trinity is one of the most difficult things to wrap our minds around and understand. In the Scriptures we find the Godhead made up of the Father, Son, and the Holy Spirit. The main point is to receive/believe by faith the existence of God in the three persons of the Godhead (Heb. 11:6). All three persons of the Godhead are distinct, separate, equal, and eternal; together they make up what is known as the Trinity.
The Godhead is referred to in Creation and throughout the rest of the Scriptures. The Trinity Godhead is clearly seen in the New Testament in the book of Matthew 3:13-17, “Then Jesus came from Galilee to John at the Jordan to be baptized by him. And John tried to prevent Him, saying, "I need to be baptized by You, and are You coming to me?" But Jesus answered and said to him, "Permit it to be so now, for thus it is fitting for us to fulfill all righteousness." Then he allowed Him. When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. And suddenly a voice came from heaven, saying, "This is My beloved Son, in whom I am well pleased." In this we see Jesus Christ the Son of God being baptized, the Holy Spirit descending on Him as a dove, and we see (hear) God the Father speaking to His Son Jesus saying, “This is My beloved Son”. We see the Trinity in Matthew 28:19, “God therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit”. We also see the Trinity in the book of Ephesians, in Ephesians 1:3 we see the Father and Jesus Christ, and in Ephesians 1:13 we see the Holy Spirit. The Trinity [the Godhead], the Father, the Son, and the Holy Spirit, is seen in other passages throughout the New Testament.
We as human beings are also triune beings [a trinity], made up of three separate and distinct parts, the Word of God reveals that we are made up of a body, soul, and spirit. In 1 Thessalonians 5:23 it says, “Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.”
Our body is the temple of God, our true house of worship, therefore we no longer need to go to special places for worship or build special buildings for worshiping the Lord. We find this truth in the book of John when Jesus spoke with the Samaritan women at the well of Jacob. Their conversation is recorded in John 4:20-24, "Our fathers worshiped on this mountain, and you Jews say that in Jerusalem is the place where one ought to worship." Jesus said to her, "Woman, believe Me, the hour is coming when you will neither on this mountain, nor in Jerusalem, worship the Father.”You worship what you do not know; we know what we worship, for salvation is of the Jews. "But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him.”God is Spirit, and those who worship Him must worship in spirit and truth."
We have a soul (the real us), our inner man or being, and we have a spirit created by God (Zech. 12:1). The truth that we have both a soul and a spirit is clearly revealed in Hebrews 4:12, “For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.”
You have been made into the likeness of God the Father, God the Son, and God the Holy Spirit, all three equal, yet separate beings, yet all three in One. You are a soul (the real you), you have a spirit that is made alive at the time of conversion (when you are born again), both of which dwell in your body, the temple [the house] of God. You are made up of three separate and distinct parts of your being, just like the Trinity [the Godhead]. Your body, your soul, and your spirit are all equal in importance and yet have separate and different functions.
