The one who says he resides in God ought himself to walk just as Jesus walked.

The one who says he is in the light but still hates his fellow Christian is still in the darkness.

The one who says “I have come to know God” and yet does not keep his commandments is a liar, and the truth is not in such a person.

If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that.
