Lets not get into wacky Jewish Talmudic doctrines. Its not a question of whether our Father, God the creator, has two or three heads. Its all ridiculous on its face. What is important is whether we have access to God, through Jesus Christ through faith that Christ is our Lord.
I primarily provide my analysis as evidence that my profession of faith isn't arbitrary or unfounded. I come from a heritage of trinitarianism and would never have dared believe anything different. It wasn't until I prayed to know the truth that it was revealed to me, and for this I am grateful, and I've found through this and other elucidations of scripture that a fuller, stronger and less confounding believing is possible.
It wasn't actually a Talmudic doctrine. It was held by the Israelites all the way back into the first temple period. But I agree, we can set it aside.
And I agree. The primary message of the Bible does not depend on Trinitarian doctrines. However I do believe it to be important for deeper understanding of our creator. But we will have all of eternity to get to know Him better and I guarantee we will all be wrong about something and will learn better when we see Him face to face.
I think all we need to know is that he is our Father and he loves us more than we can fathom
I think we also need to know that we are sinners incapable of living up to His standard and yet He provided a way for us to live with Him for eternity regardless of our failings.
Before we are saved, yes. After we are saved through Christ, we can strive to perfection.
Yes, we strive for perfection. However we will never reach it this side of our resurrection.
Yes, Confession is key.
"If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness." (1 John 1:9)
We are not righteous in ourselves or our deeds:
"as it is written, “There is none righteous , not even one ;" (Romans 3:10)
All of our righteousness comes from Jesus:
"He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him." (2 Corinthians 5:21)
