I liked this quote from Bruce R. McConkie:
In other words, true and perfect worship consists in following in the steps of the Son of God; it consists in keeping the commandments and obeying the will of the Father to that degree that we advance from grace to grace until we are glorified in Christ as he is in his Father. It is far more than prayer and sermon and song. It is living and doing and obeying. It is emulating the life of the great Exemplar.
