To me, Scriptures are like a multi-faceted diamond. What each of us sees depends on the facet we are facing. But it is the same diamond (words of God) and the same Light (God.)
If Jesus wanted us to agree on every detail He could have made it so by giving us not only the indwelling Spirit but identical minds to hear and follow Him. Or He could have chosen twelve with the same mind.
Instead He chose twelve very different men.
Peter was not like James who was not like John who was not like doubting Thomas, etc.
Each of them seemed to have a different perspective - they were facing different facets of the diamond. (Personally, I would like to have John's perspective because he was focused on the Person of Christ.)
If they were cookie cutter Christians then there would not have been a council in Jerusalem and Paul would have had no dispute to bring to their attention. And Paul and Barnabas would not have parted ways. But because they did the Gospel spread further faster (Acts 15)
So, in my view, theological differences are within God's will provided we are looking at the same diamond (words of God) and have the same Light (God.) Differences would not be acceptable among people who disagree on Who God IS or cannot hear the words of God at all.
To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out. And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. And a stranger will they not follow, but will flee from him: for they know not the voice of strangers. – John 10:3-5
[There is] therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. - Romans 8:1
But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. - 1 John 1:7
