'Love' in the Bible

The elder to the chosen lady and her children, whom I love in truth; and not only I, but also all who know the truth,

Grace, mercy and peace will be with us, from God the Father and from Jesus Christ, the Son of the Father, in truth and love.

Now I ask you, lady, not as though I were writing to you a new commandment, but the one which we have had from the beginning, that we love one another.

And this is love, that we walk according to His commandments. This is the commandment, just as you have heard from the beginning, that you should walk in it.
