Understanding the doctrine of the Trinity is difficult for most people. There are even some who think those who believe in the Trinity believe in three different gods, making them polytheistic in their belief instead of monotheistic; “poly” meaning “many,” “mono meaning “one.” But understanding the Three in One of the Godhead brings clarity to the Scriptures and a greater love for Who God is.
Within the Trinity there is God the Father who is the Creator and Sustainer of all things, God the Son who became the Sacrifice for sin, and God the Holy Spirit who indwells each believer who comes to faith. All are the One True God manifested in three different ways. An earthly way to describe the Trinity, although woefully inadequate in its description, is how one person can be a father, brother and son all at the same time, or how one person can be a mother, daughter, and sister all at the same time. The person is not three distinct, individual people but one person relating to others in three different ways. That is the way the Triune God is, Three in One, although God relates wholly as Father, Son and Spirit at the same time.
According to Scripture, on creation morn God the Father (Genesis 1:1), God the Son (John 1:1-10), and God the Holy Spirit (Genesis 1:2) were all present when it was said “Let there be light.” When man was formed out of the dust of the ground God said “Let us make man in our image, after our likeness,” referring to God the Father, God the Son and God the Holy Spirit (Genesis 1:26). On Calvary’s cross God the Father (Luke 23:46), God the Son (I Peter 2:21-24), and God the Holy Spirit (John 14:16-17) were all present. At salvation God the Father (Romans 5:8), God the Son (Romans 6:23) and God the Spirit (Ephesians 1:13) are all present as One.
Before going to the cross Jesus tried to explain the Three in One to the disciples in John 14, “Believest thou not that I am in the Father, and the Father in me?… Believe Me that I am in the Father, and the Father in Me.” In John 16 Jesus continued, “Howbeit when He, the Spirit of truth, is come… He shall not speak of Himself… He shall glorify Me.” To believe in the One True God, you must believe in the Trinity. For without believing in any One of the Three in One, you cannot have a belief in God. They are All One; All part of the Godhead.
Three in One;
The Triune God.
