Whoever says, “I know him,” but does not keep his commands is a liar, and the truth is not in him.
In context
2He himself is the atoning sacrifice for our sins, and not only for ours, but also for the sins of the whole world. 3This is how we know that we have come to know him: if we keep his commands. 4Whoever says, “I know him,” but does not keep his commands is a liar, and the truth is not in him. 5But whoever keeps his word truly has God’s love made complete in him. This is how we know we are in him. 6Whoever claims to remain in him ought to walk just as he walked.
