34. a new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another--This was the new feature of it. Christ's love to His people in giving His life a ransom for them was altogether new, and consequently as a Model and Standard for theirs to one another. It is not, however, something transcending the great moral law, which is "the old commandment" (1Jo 2:7, and see on Mr 12:28-33), but that law in a new and peculiar form. Hence it is said to be both new and old (1Jo 2:7, 8).
