Lust kills for what it wants. Love is willing to be killed for what it wants.
We are in 1 John chapter 3 verses 11 through 15, discussing the differences between the love of the world and the love of God described in His Word, and how God does not only declare to us and define to us what true love is, but also can develop in us that same love by His Spirit, according to the Scripture. Loving people should not get in the way of our love for God. It is the way to love God, and He is the way to love them.
