Faith Alone?

Many Christians claim that "faith alone" saves and that there's no need to lead a righteous life.  I just want to ask them all, "are you sure you shall be saved?"  I am more than sure that their case will be worse than that of atheists. They're just using Jesus to promote sin!  They think that a simple faith in Jesus is the greatest thing a person can do on earth; it is by "GRACE" a person is saved and not by "FAITH". If a person is to receive God's grace, he should be righteous and should be following the words of God. By following the words of God alone one can prove his "faith" in God. It is not "knowing" Jesus' sacrifice that saves, but following the path he has shown that leads to salvation by grace of God through Jesus. Unless there is true faith (evidenced by following Jesus' words), no one can attain salvation. God is a righteous God and he loves righteousness.
The criminal who died with Jesus and saved is an example for a person receiving God's grace through repentance. It was his repenting mind that brought him salvation; not his faith. Faith without repentance and obedience means nothing. Hence, do not mislead people by letting them live in sin without fear of God since Jesus has died for them. No one shall be saved that way; the sacrifice of Christ is for those who truly repent and obey God.

My Reply:
My friend, I hear you, but I think you've combined salvation and discipleship into one.  We are saved by grace through faith in Christ Jesus. But it doesn't stop there, and this is what I believe you're arguing.

Dietrich Bonhoeffer has a book called "The Cost of Discipleship", that I think you'll like, for it talks about this. Many Christians today promote what Bonhoeffer calls "cheap grace". They accept Jesus, but continue in their sinful ways. They figure they're saved, nothing can harm them, back to business. But this isn't what salvation's about.
Salvation in Christ is what Bonhoeffer called "costly grace", for to be called by Christ is to be called to come and follow in His footsteps, even to the cross (if needed). 
I did a Bible study the other day where I learned that the word used for Peter's denial of Jesus is the same word that's used for when Jesus said that in order to be His disciple, one must first deny himself.  Same word, same type of denial, same impact.  Those who practice costly grace understand this.  Those who practice cheap grace might say they do this and agree with you, but obviously don't practice it.

James said faith without works is dead, and one of the main frustrations in the early Church was idle Christians. Unfortunately, we still have a similar problem in the Church today.

So yeah, you're on target, but I think you need to reword your question. Check out that book, too (linked below).
