Obedience is Evidence

John declares that authentic faith produces obedience. Those who truly belong to God listen to his voice and obey him. John states bluntly that anyone who claims to know Jesus but shows no interest in doing what he taught is a liar. There is no such thing as authentic faith without obedience. John gets even more specific, explaining that whoever claims to know Jesus must live as Jesus did. Authentic believers become more like Jesus throughout their lives. This transformation is supernatural evidence of salvation because becoming Christlike is impossible through human effort alone.
