The way we can be sure of our knowledge of Christ
is to keep his commandments.
The man who claims, “I have known him,”
without keeping his commandments,
is a liar; in such a one there is no truth.
But whoever keeps his word,
truly has the love of God been made perfect in him.
The way we can be sure we are in union with him
is for the man who claims to abide in him
to conduct himself just as he did.
