Your response, Teresa, and Daniel read's appear next to each other on my screen; they show two sides to the matter of "feeling" when it comes to worship, and to love.
The love of God moves the emotional part of us -- almost to the point that we make love to be an emotion. Feelings, however, are changeable, where love is not changeable. A person can never "fall out of love" with anybody they love, because if you love someone, you won't abandon the love!
Now this is not like Duty. "Doing" worship -- actively deciding to worship God, even when feeling mad, disappointed, confused or bored by Him -- is something deeper than Duty. Duty can be accomplished by a trained horse for carrots; love is responsive and creative in every situation it meets.
We may show God we love him by caring for a smelly person who is bad-tempered. Doing such an act of worship may be very pleasing to God, but we may not enjoy it at all, and may even remember the time with disgust. But we followed through because we had compassion -- something that has close ties to feeling, but is better than feeling.
