The Merriam-Webster Dictionary lists the following twelve words as either analogous words for worship or synonyms of worship:
adore, admire, dote, esteem, exalt, love, magnify, regard, respect, revere, reverence and venerate.
This is what the english word worship means. It is the adoration, veneration, exaltation and magnification of God. It is when we respect, esteem love, admire and even dote on God that we are worshipping Him. Quite obviously, worship is totally concerned with the worthiness on God, not the worthiness of the worshipper.
