However, there have been some preachers claiming to preach grace, who, in an attempt to make grace amazing, end up distorting it, turning people from a diligent pursue of God to an lukewarm Christianity. They might seem on fire but I would rather say it's fervent lukewarmness.
Grace does not mean that you don't have to put any effort into your spiritual growth; it means that you are getting something you were not able to attain by your own strength. Grace is getting something you don't deserve because you are not worthy.
WHO SAID YOU DID NOT HAVE TO DO ANYTHING?
Some might say: "Well, did Paul not say that we are saved by grace and not by the works of the law?" Yes, Paul was preaching salvation by grace and not by the works of the law, but he was in no way promoting a lazy attitude towards living the Christian life.
