When love is expounded upon in Matthew 22 and Leviticus 19, the expectation of love is not related to how I feel, but by who God is. Therefore love that is referenced here is not rooted in a particular emotion, but a by recognition of God's action. How that relates to our neighbor love is a reflection of God's action in the world. A principle part of God's creation is humankind created in God's image. That is the challenge of love, when I expect emotion, God expects that we act toward our neighbor with the understanding that the other person is created in God's image.
