I have heard many people make statements that they do not feel that the old testament of the bible applies to what is going on today, or that we are under the new covenant and so why do we need to read it. But let me explain the importance of the old testament in our lives even now in 2020.
First and foremost the bible is the truth and every book of the bible is ordained by the Spirit of God. We are not to remove or add to what is in the bible. Which brings us to one important truth. If we are not to remove what is in the bible then that means that the old testament is just as important as the new testament. Yes we are under the new covenant, yet when we except Christ Jesus as our Lord and Savior, we are now included in the promises that were made to the Israelites. Failure to read the old testament would cheat you out of promises that God has made for us to obtain as well as the Israelites.
The next importance is that there is history and every time you read through the old testament you see patterns that start to be revealed. You see Gods promise if his chosen people will worship only the One True God and no other gods. You see how much God loves his chosen people, yet we see the Israelites continue to rebel against God and we see what eventually happens as God brings correction just as a loving Father would do.
My goodness the idolatry, adultery, murder, etc. happened all through the time of creation. The people making it all about what they wanted, and chasing after the things of this world, rather than chasing after God. These are the same things that are happening now in 2020, it is no different. People were sacrificing their children to the God Molach, which is no different than what is happening now. We just call it abortion in this modern time. So you can see that yes the old testament does apply to 2020 just as it did thousands of years ago.
We can see the heart of God, when a King repents for the sins they have committed and God shows grace and mercy upon the people withholding punish at that time. If you don’t read about it in the old testament it would be lost forever.
There is a reason that God gave us the old testament for we can see the way that the prophets, and psalms point to Jesus as the Messiah, the Savior of the world. Just the other day I was struggling with some things and I was talking to the Lord and asking to hear from him. I then hear Isaiah 45 and I find new revelation as I read through the whole chapter, looking for treasure under the rocks. God has so much that he wants to reveal to many.
