It seems tho...what we should preach to them should or must be limited to A and B...leaving C and D.
You mean, some people are less sinners than others? I think if we read Isaiah 53, the Epistle to the Hebrews, etc., the context is clear.
No: A and B would be what they'd want to hear while C and D are those teachings about HIM they would not want to hear (these are false teachings to them).
There was no NT in the days of the Apostles and Jesus. They quoted the Holy Scriptures and the fulfillment of them. Such as Joel, "in the last days God will pour out His Spirit..." God also spoke of New Covenant that would be written on the hearts of the people. David spoke of one he called Lord sitting at the right hand of God. Are those lies?
One might state "I am offended by the gospel message"
Answer: But that doesn't make it a lie
I don't think many understand the severity of the consequences in rejecting how God chose to forgive sin. (Its not for man to choose how to forgive sin)
The gospel message better explains the absence of a High Priest on earth then what current Judaism teaches people.
So its a work of love to help anyone come to God for their salvation. But one must be willing to listen. We can reason with scripture.
