'New Commandment' in the Bible

I am giving you a new commandment: love one another. Also you should love one another in the same way that I have loved you.

My dearly loved ones, I am not writing to you about a new commandment, but about an old one. [It is the one] you had learned about from the beginning. [Note: This is the commandment to love one another (3:1: II John 5) which Jesus had taught his disciples during His earthly ministry. See Mark 12:31]. This old commandment is the word [of God] which you heard [previously].

Yet, I am [also] writing to you about a new commandment [Note: This commandment was to love one another as Jesus loved them. See John 13:34]; its truth is [being demonstrated] by Christ [perfectly] and [also] by you people [in a lesser measure], because the darkness [of sin] is passing away, and the real light [of righteousness] is already shining [in people's lives].

And now I ask you, lady [See verse 1], not as though writing a new commandment to you, but [I wanted to remind you of] one that we had [heard] from the beginning [of Christ's ministry]: [It is] that we should love one another.
