Salvation is by grace alone (Rom 6:23; Eph 2:8-9), through faith alone (Rom 3:28; Gal 2:16), in Christ alone (John 14:6; Acts 4:12), totally apart from works (Rom 4:4-5; Eph 2:8-9; Tit 3:5). However, after salvation, the Christian is called to a life of obedience, not as a means of securing salvation, but as the proper response to divine grace.
