Worship God or Our Feelings About Him?

I just read Emotionally Healthy Spirituality by Pete Scazzero. In it he talks about when we hit a wall spiritually, and discusses St. John of the Cross and his famous teaching on “the dark night of the soul.” I love what he says here:

St. John of the Cross knew our tendency to become attached to feelings of and about God, mistaking them for God himself. These sensations, rich or empty, are not God but only messengers from God that speak to us of him. There is no other way, John of the Cross would say, for our souls to be strengthened and purified so that we don’t worship our feelings than for God to remove them altogether. This is God’s way of rewiring our taste buds that we might taste of him even more fully.
