John, the apostle who wrote this gospel, later wrote about the new commandment of love. No doubt, he received his inspiration from this teaching of Jesus. John wrote, ‘Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning. Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth’ (1 Jn. 2:7-8). He then goes on to speak of loving one another.

This commandment, or the revelation that God gave to man through His Word, wasn’t new, but was never clearly seen by men because of the darkness that separated them from God. In the light of Jesus’ life, the darkness was removed and the old commandment of love became new through the example of Jesus in a way that mere words could never express.
