Why is it that some people can merely just say they believe in Jesus Christ and think they are going to heaven? Is it self deception or are they blinded by Satan? I think it's a matter of both.
Being born again will bear the fruit of a new lifestyle. Do not deceive yourself into thinking that lip service will get you to heaven. We are saved by faith in Christ alone but regeneration will take part in the lives of those who are truly saved. God WILL transform you beloved!
John 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
"Good people" don't get to Heaven, only saved ones do. Are you saved from your sins by true faith in Jesus Christ?
