There are people who want us to believe god had to purify Himself but that we ourself do not have to do any works any more or can do whatever we want because God brought salvation to us by His death, though God can not die. By such misleading teaching those 'preachers' are fooling not only themselves but are taking the opportunity away for others to find the Real God of gods and the entrance to the Kingdom of God.
When men let their faith and confidence in the credibility of the Word of God get away from them, there is danger of lowering their ethical standard. A tottering faith in the Bible narratives shall bring morality to be unstable and to stagger also. When there is a rejection of the integrity of the Old Testament narratives there shall be no vibration to come to see the truth of this life and the person shall move or sway unsteadily or unsure in this materialist world were more and more people are moving away from God and are having their egoism being the base of their life disturbing their relationships, making them unstable.
The Bible show us The Being Who makes us able to be a being. The collection of 66 books focus on That Most High Being without Whom no being or existence is possible. The Words of God are there to mould or form each creature of God. By allowing that Word of God to form us we can become reconstituted or 'made anew' by the Former God.
Since the 19th century the people who very suspicious because they did not see historical evidence could find one city after another, one civilization after another, one culture after another being found and restored to their proper places in ancient history by the studies of archaeologists and Bible scholars like Botta, Layard, Wellhausen, Winckler, Taylor, Archer a.o..
There are no proven external defects in the witnesses all those Biblical authors and contradictory to the adversaries their sayings and writings, no internal defects in their testimony can be found either.
We can look at the biblical authors as Witnesses for Jehovah God, the divine Creator of many universes, as people who were called to testify before humankind and in several occasions were even willing to give up their life for what they considered to be the truth.
