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.
Not many believers may considered wise or powerful according to human standards, or may not being 'well born' or from "blue blood". In the Scriptures may be found many words also from foolish men. Many wrong actions of men are notated in the bible so that people can learn from them. Those foolish things of the world God chose in order that He might put to shame the wise, and the weak things of the world God chose in order that He might put to shame the strong, and the insignificant of the world.
Contrary to the sayings of KJV-only people, God has given His Word to all people in whatever language they speak and for eternally shedding light on His righteousness and honesty, His Word never telling lies. The Supreme Power also enables us to compare His Word like we can find it in print these days, with the ancient writings and original manuscripts which have been discovered by archaeologists after the 17th century.
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.
