I always wondered why God let us fall apart as we age. I now realize it’s so when we die we think Thank God that’s over.
The PLAN was for us to live forever with God in the Garden of Eden. He even warned Adam and Eve that sin would bring death.
BUT - as your post alludes to - that death is by the grace of God. Can you imagine having to live FOREVER in this fallen world separated from God, living with evil people, deteriorating bodies, etc. So yes - we WILL thank God for our deaths, but also the good things in our lives. And most of all thanks for the redeeming salvation He provided in the death and resurrection of His only son Jesus Christ.
