"For there are three that testify..."
(1 John 5:7).
God is a Trinit yet one God. God is in three persons; each person is divine; there is only one God. God is one but three distinct characters/ personalities. God as the Father, God as the Son, God as the Holy Spirit. They are not three separated gods but they are one God. Each of the persons is distinct from the other, yet identical in essence. Each of three persons is divine. Each of three persons has emotions and feelings, they speak, love, communicate and can be hurt. Each is not the same person as the other. But there is one God. Each of the persons in the Trinity share the same attributes. In all universe exists a single being known as God who is self – existent, created all things, is omnipotent, is unchangeable and just.
The Father always is first, the Son is second, and the Holy Spirit is third. The Father is not begotten, but the Son is.
The Holy Spirit comes from the Father. (John 15:26).
The Father sent the Son (1 John 4:10).
The Holy Spirit sanctifies (Rom. 15:16).
We as limited human beings are not capable understand this mystery but some say this is similar in analogy to the nature of time. Time is past, present, and future. The past is not the same as the present, which is not the same as the future. But there are not three times. There is only one thing called time. It could be the same as we humans are three parts - spirit, soul and body. So God is Father, Son and Spirit.
The truth is we do not have to reason about Trinity too much because some things are just as they are, and we will know and understand them in proper time. The word Trinity is not found in the Bible and actually no one can explain it fully. Using word Trinity mere human is just trying to explain and understand God. But how than, limited, finite, restricted human being can imagine to understand unlimited, absolute, infinite God!?
“May the grace of the Lord Jesus Christ, and the love of God the Father,
and the fellowship of the Holy Spirit be with you all”
(2 Corinthians 13:14).
