[Ali Imran]

The only basis for salvation is the work of Jesus in and through His life, death, and resurrection, and the only means to salvation is trust in Him. The good news of the gospel is that based on nothing we have done and everything Jesus has done - by His grace alone, through faith alone in Him - God will declare us right before Him. In this way, the gospel frees us from any and every attempt to earn God's acceptance through our work.

What if a man only follows the teachings of Jesus but not Paul? This means that he doesn't believe what you believe pertains to salvation.
