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.
Though many things may be very difficult to proof that does not mean that they would not exist. Also feelings and experiences are difficult to proof, though the results of a God-Being in our life is something what many feel. One thing is for sure: "If God does not exist, then everything is permitted". In the transcendent reality we can not see nor fully understand God but somehow looking around us and listening to our inner feeling each person should be able to come to recognise the Supreme Power and to understand that reality is shaped by a Power beyond us.
The Elohim wants people to have a willingness to hear His Word Which He offers as a schooling-tool enabling all people to get insight and wisdom. Most of the time people did not want to listen to His word and preferred to follow their own fantasies or what they thought would be scientific right. As such we got creationists, flat earth believers, and many others, who after science brought some proves still did not want to believe it.
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.
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.
Only by a Most High Supreme Being that existed for ever causing everything to come into being, the being only can be a reality and as such to be a truth when that Eternal Causer, Provider and Most High Supreme Being is a realistic existing Thing or Personality. We must come to believe in Him and His Words calling for things to come in order from the chaos and His breath to be the life giving element. Even when there may have taken an evolution over a long period of time, looking at the complexity of all things we should be in awe and have more faith in a Master-hand behind everything, coming to see that without this Master Creator or Godly Designer has provided for life and consciousness having made beings to come to be able to think, handle and talk like human beings do.
To come to a faith life of truth we will need a solid foundation. to explore the truth one is best to use a trustworthy book. It may look strange but there is a Book of books, containing 66 books by 40 authors which is literally of extraterrestrial origin.
