When a person is saved, it is sealed with the indwelling Holy Spirit.. Can man break the seal of Holy Spirit put by God? That is why once a person is saved, he is always saved.. Because man cannot change God's will.. If someone is using grace as an excuse to sin, they have not understood what salvation is.. And he or she is not really saved..
