1 John 2:5-7

Revised Standard Version

⁵ but whoever keeps his word, in him truly love for God is perfected. By this we may be sure that we are in him: ⁶ he who says he abides in him ought to walk in the same way in which he walked.

A New Commandment

⁷ Beloved, I am writing you no new commandment, but an old commandment which you had from the beginning; the old commandment is the word which you have heard.
