Obedience to God and Christ is love...
1Jo 5:3 For this is the love of God, that we keep His commandments, and His commandments are not burdensome.
I disagree especially with reference to the Scripture you quoted. I believe the most one can say is "obedience to God and Christ is evidence of love."
John 13:34
A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another.
Ephesians 2:15
by abolishing in his flesh the law of commandments and ordinances, that he might create in himself one new man in place of the two, so making peace,
1 John 2:7
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.
2 John 1:5
And now I beg you, lady, not as though I were writing you a new commandment, but the one we have had from the beginning, that we love one another.
The Apostle John also said, "Little children let us love one another, for love is of God."
