The problem with wordy explanations is that the mind is absorbed in an intellectual exercise only and it becomes devoid of Spirit. It becomes a work of the flesh. The scriptures are divine inspiration therefore that is good but then interpretation is added and this is distorting and a difficult mental exercise. This can take the life out of a relationship with God because this is Spirit. Did Jesus ever write anything?
Everything that has been shown to me is direct. I was shown within my mind how my mind did not measure up to the mind of an immortal, the mind Jesus thinks from. This is where sin is hatched from.
I was shown how the same mind could be attained to and immortality is a possibility and hope.
At this point there was no atonement or at one with God, but there was grace. I had been given a quick, very short look beyond the veil in the mind and it placed me in some shock.
At that time the understanding of the temple with the sanctuary was not understood. I had never read the Bible but had known some Christians at work and had heard stories about Christianity generally.
I thought the God that had been revealed powerfully and of the Bible was the God they spoke of.
Years later when a fast was taken the Spirit that was some what withered and dormant revitalized a belief.
Simple prayers, and a work of faith developed a deepening real belief in the heart and some purity began to be attached to words of scripture and revelation as they were spoken out. This eventually lead to the exposure of a realm of the mind that was full of attachments or fixtures (demons) that were in control of my will. These determined my behavior in any situation and the emphasis on words as they were delivered in conversation.
This came from inside and this was established from the company that was being kept. It is even in the responses to own close family. A human does not truly Love because it is usually conditional. Everyone is bonded in familiar emotions.
Atonement occurred when I broke inwardly deeply enough in an act of laying every last bit of my own self aside and then the nature of Jesus settled over me. This nature is unconditional Love and it is energized by God. There is no sin in this nature because it is perfect and it is acceptable to God and He indwells. My will was released from the influence of my own self and then it was one with the will of God. That is atonement, at one with.
The temple is the body and the example is that the 10 commandments on stone tablets were in the ark under the mercy seat with the cherubim. The heart of stone, the law, is replaced by one of flesh. There is actually a release around the heart area in the chest as all the old encumbrances on the personality fall away. This is circumcision of the heart.
The nature of Jesus is impossible to imagine because of its gentleness and quietness.
"Jesus is an atonement for your sin" as you write is not functionally correct. Atonement is to place -at one with- By example Jesus through His sacrifice has revealed the way back to God.
1 John 2:2 Jesus is an atoning sacrifice for our sin and not just ours but for the whole world.
Jesus is Our Advocate
…
4The one who says, "I have come to know Him," and does not keep His commandments, is a liar, and the truth is not in him;
5but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him:
6the one who says he abides in Him ought himself to walk in the same manner as He walked.
If the heart is changed and the Love of God is perfected the words spoken will be truth and will impart some power of unconditional Love energized by God. This is what everyone falls short of. Everyone is still playing in the mud puddle of a mixture of thoughts and reasoning.
