Question 2
What specific warning does the Bible give for people who are interested in following the Bible?
Bible
Matthew 24:4-5
"Beware that no man deceives you. Many will come in My name and will deceive many."
Bible
Matthew 7:21
"Not everyone who says "Lord Lord" shall enter into the Kingdom of Heaven."
Bible
Acts 20:30
"Men will rise up, speaking perverse things, to draw away the disciples after themselves".
Answer
It was Jesus himself who gave these warnings in the book of Matthew. Saying “Lord Lord” or just claiming to be a Christian isn't a magic formula that will automatically get you into heaven. Jesus Himself warned again and again to watch out for deceptions. People will come claiming to be on God’s side in order to deceive many. And others will come teaching strange and "perverse" things (including evolution) to try and draw people away from following God's word.
