I am no theologian, nor do I wish to engage in theological arguments. But the best way I know to build a personal relationship and understanding with/of God is through His Word. I strongly suggest getting a hold of a version other than KJV, such as the New International Version, Revised Standard Version, or the ESV. Another thing that helps me is One Year Bible Online. This app provides daily readings selected from the Old Testament, New Testament, Pslams, and Proverbs. You might want to start this on 1/1/2023. There's audio with commentary or you can just read the verses for yourself. Try to edit out all the guano and legalism you have previously learned as you listen/read.
God bless!
