The Bible contains messages that pertains to life and death. We need to look at both sides. Sometimes when we focus on the negative side it will bring us to despair and depression. And when we focus on the positive we might think all is ok and we have no accountability.
The Book of Ezekiel contains both. Although it talks about sins and evil it also talk about promise and restoration.
Here is the promise: Ezekiel 11:19-20 I will give them an undivided heart and put a new spirit in them; I will remove from their heart of stone and give them a heart of flesh. Then they will follow my decrees and be careful to keep my laws. They will be my people, and I will be their God.
There is also a warning : Ezekiel 11:21 But as for those whose hearts are devoted to their vile images and detestable idols, I will bring down on their own heads what they have done, declares the Sovereign Lord."
The promise I believe is fulfilled when we come to Jesus Christ for the forgiveness of our sins and then God gives the Holy Spirit to us so we can be His people and He will be our God.
