Greeting Oddawll2 and welcome to this forum. And welcome also to the family of God. It is wonderful that you are reading the Bible in a manner and with a motive to cover truth, rather than as an exercise to discredit or malign.... That of itself is sufficient evidence of your genuine conversion.
Now at the risk of raising the ire of other members here who may disagree, I would like to propose one or three basic principles that may help you to understand the scriptures, at least in the basics. No-one expects you to earn a doctorate in divinity... Ever... so don't sweat not getting it.
First point. The Bible is not word inspired. There are some minor discrepancies between the eye witness accounts we read of Jesus life in the gospels... Which is to be expected because you have different people seeing the same things but from different perspectives. This is all in God's order in order that we may gain greater insight into the events thus described. Police love this when presenting a case. 10 witnesses giving exactly the same evidence creates suspicion of collusion... so slight differences in the gospels give more credence to their validity and truthfulness. So, not word inspired, but most assuredly thought inspired. Inspired by the holy Spirit the writers of scripture, including the prophets of the Old testament, wrote in their own words the thoughts and principles that God revealed to them.
Secondly, about the Trinity. The Trinity, as a word, is not found in scripture. Scripture uses the word Godhead... Which is my preference. God is God. He is unexplainable, except in those areas He has been pleased to reveal. What we know is what we are told. When people attempt to explain the term Trinity, they invariably need to use expressions and concepts that are not found in the Bible. To my mind, if a concept itself in unexplainable, and those promoting it cannot adequately explain it in a way any else can understand, it is best left alone.
What we are told, in its most basic fundamental form is adequate. That God is a Father. That Jesus is His Son. God says Jesus is worthy of worship... Obviously because of His Sonship. The holy Spirit is described in the scripture as being the Spirit of God, and the Spirit of Jesus, sometimes in the same sentence. The scripture also says Jesus was the vessel through Whom God the Father created all things... Therefore the Sonship of Jesus goes back to a time before creation. We are not told how long. Nor are we told the Son is as old as the Father as the Trinity attempts to teach us. A Son the same age as His Father is simply not logical. And God is logical, and has described his identity in ways that are logical and in harmony with our admittedly finite minds. It is dangerous to go beyond that. I could go a little deeper, but the above I think is sufficient to give you somewhat of a broader perspective of what you are getting yourself into. The Trinity, despite the creeds etc that demand it is a doctrine all Christians must accept to avoid being labelled heretics or non Christians, is an essence an assumed doctrine. Assumed doctrines should never be doctrines.
