To my mind, there are a few reasons for the lopsided view of NT/OT scripture. Part of this has come about by late 20th century views on end times and evangelism.
During the Reformation, the whole of scripture was to be received in faith, as being the whole counsel of God. The scripture were viewed as God’s revelation of Himself throughout the history of humanity… into the transition of the New Covenant…God with us, in the person of his Son.
The book of Hebrews is so important to believers in setting forth the continuity of the Old Testament (Covenant) into the New Testament (Covenant.)
Mixed in with this subtle divorcing of the Old Testament from the New Testament within mainstream Christianity…is the secular view of “love”.
Throughout, the OLD testament…God’s consistently reveals His love…It is in the garden after the fall, it is revealed in Noah, it is revealed in the promise made to Abraham…”In thy seed shall all the nations of the world be blessed.” We have faith and confidence in Jesus…based on the promise made to Abraham. We see God’s love throughout His relationship with the nation of Israel. We see His love toward the ungodly, pagan nations, in that He did not destroy them, “until their iniquity was full”…meaning there was no longer any hope of them turning from the corruptness, the vileness of their ways.
I would like to park on this for a bit, to illustrate what I mean. I have been no different than anyone else in wondering about the whole sale slaughter of people groups in the Old Testament… It seemed incongruent with a God of Love. Then, in my walk as a believer, I began to experience the long term effects of the sins of my fathers…generational sin…Intense misery, bondage, grief, sorrow, inability to function “normally”. I pleaded with God to “take me out” and I came close to taking myself out because the mental/ emotional suffering and pain was beyond my ability to cope with. I wrestled and struggled with God. I earnestly questioned…in my agony…”why me?” “I haven’t done what my forefathers have done…and I am suffering the consequences…” Other believers could not relate to the hell I was going through. But, God is sooo faithful. I asked and he eventually answered all my questions. I could see from my own personal experience how very painful, (really quite impossible) it was for me to live “normally”, and that was with His saving grace. I began to look back on those Old Testament stories and see them in a different light.
God allowed things to go to a point…then, that was it! He knew without the power of Christ in the gospel…there was no recovering from the wickedness that children were growing up in…and that they could and would only become as vile and corrupt…There wouldn’t be any other option for them.
Take for instance the increasing sexual abuse and exploitation of children in our present time. I am one of those…and I know…it is a living hell and totally destroys vast parts of a developing human being. Those who seek to rescue expolited children know…it is very difficult to bring them back from the wholesale damage done to their psyche.
Now think of a pagan culture…of generations of this type of wickedness, generation after generation, one after another…deeper and deeper into the horror. I believe God was merciful in destroying those cultures. Their lives were abominable! (Even to themselves.) There would have been no good…just misery.
As I reflect on these thoughts, I am glad that God in His infinite wisdom removed the evil …even it if meant removing many souls in the process. Evil is a contagion…
We lock people up in prison…because we know some people will not cease from doing evil and will destory many other lives in the process.
As a culture we feel completely justified in doing so, for the good of those who are not a danger to others.
So, let’s move on…God continued to show his love…over and over to the nation of Israel…even in his judgements and chastisements. He kept His Word and has fulfilled His promises to Abraham, Issac and Jacob…in Jesus. Emmanuel, God with us, was born of a virgin, conceived of the Holy Spirit, so he would not inherit Adam’s sin nature…He lived a perfect, sinless life, for us…because we cannot…He laid down His life for us…so, our sin nature might be put to death in him…and He rose again, because sin had no claim on him! The resurrection proves…his sinlessness…Death could not hold him…Now he lives in heaven to intercede for us…Plus, in his great love he has poured out His Holy Spirit into the hearts of all believers…
God’s love…His justice, His mercy, His righteousness, His goodness, His kindness, His faithfulness, His power…manifest…throughout the OLD and New Testament. Do we hsve a better Testament than the Old…Absolutely! But, let’s not diminish the whole counsel of God…
Withiut the Old…there cannot be the New!
Right now, I am not able to provide all the scripture references, for what Inhave said…as I am away from that resource…But, as we know from Ephesians, God planned before the creation of the world, to reveal his love to us in Christ.
