Is it because we have grace today and David didn't?
Would people like you and me have known about these things with David, if we had been alive then? If not, how do we know God doesn't do the same things today?
I don't know, people quote the old testament about healing the nation, USA; doesn't that mean they believe that God still operates the same way He did in OT times? That God judges nations by their laws and behaviors of the people in the nation, both the saved and the unsaved?
Good morning Debora,
I'm not sure where you stand and you may have just siad it without fore-thought but King David was and is saved the same way any of us is saved, by the unmerited grace of Goid/Jesus. The Ten Commanndments never saved anyone and even Father Abraham was held in Paradise until Jesus died on the cross and released the entire lot of them to go to Heaven and then, only, after they had appeared in the streets of the Holy City of Jerusalem. (Matthew 27:50-53)
I was taught, early on, and do teach that Jesus went into Paradise to preach the Gospel of the Salvation by Grace to them before they could follow Him into the presence of God.
It is my opinion, from my studies on the Evolution of the languages, that when the older statements of faith place Jesus in Hell they are speaking of the Grave, perhaps from a closer understanding of the ancient words than we, generally, hold today. Of course we know from the knowledge of the scriptures that when we, humans, are placed in the grave, ¿Hell?, our souls, the Spiritual Being inside our bodies that is ourselves, goes, immediately, to be with Jesus in Heaven. (Rev. 6:9-11)
Now your very astute question about God operating the same as He did in the time before Jesus. The answer is found in Mal. 3:6a, God is the same today as He was yesterday and He is the swame today as He will be tomorrow. We still teach our Children andour Youth the Ten Commandments because God has not changed. The study of this, particularl, doctrinal truth is a very slippery slope if studied without the hand of a teacher on one's sholder.
When I took the Grumpy Old Men's Class, I was teaching how to live a Holy Life, separated to God alone, and when I arrived at this point in the study is when my class fell from fourteen to three and one of the three a new member after the click had followed the one man to another, local, church to get their ears tickled. This idea that God never changes can slide into so many different niches that very few will, even, teach it. I've witnessed more than one Pastor of a Church refuse to teach this, the book of Revelation and Dan. 10 thru the end because they are so difficult to grasp.
Praying this helps a little for your understanding.
