Righteousness by Faith

Read carefully :) 

"For it is by grace you have been saved, through faith, and this not from yourselves.  It is the gift of God - not by works, so that no one can boast." - Ephesians 2:8-9

"We maintain that of whatever kind a man's work may be, he is regarded as righteous before God simply on the ground of gratuitous mercy; because God, without any respect to works, freely adopts him in Chris, by imputing the righteousness of Christ to him as if it were his own.  This we call the righteousness of faith, that is when a man, empty and drained of all confidence in works, feels convinced that the only ground of his acceptance with God is a righteousness which is wanting in himself, and is borrow from Christ.  The point on which the world goes astray (for this error has prevailed in almost every age), is in imagining that a man, however partially defective he may be, still in some degree merits the favour of God by works... God reconciles us to himself, from regard not to our works, but to Christ alone, and by gratuitous adoption makes us his own children instead of children of wrath.  So long as God regards our works, he finds no reason why he ought to love us." - John Calvin
