Of course there will be those in any group who do not display a correct attitude.
However, that doesn't negate the fact that Calvinism correctly stresses that salvation is a gift of God. This is a doctrine which is taught plainly in the Bible, is also evident in natural theology, and one that brings solid assurance to a believer.
One must base his/her theology on any truth that is evident and not fallible people who may be attempting to espouse that truth.
True enough
“Calvinism stresses that saving faith is a gift of God.”
All Christians agree that salvation is the gift of God (Eph 2:8), but not all agree that God gives saving faith to some, while hating others and not allowing them to believe.
The problem is that many FR Calvinists go further and claim that man has no chice in his salvation and that if man can choose to either accept ot reject Christ, it means that man can save himself and is then a "work" rather than a "gift." They overlook the fact that gifts can be either accepted or rejected.
