Greg Laurie writes on worship in today's Harvest Devotional:
A number of words in the Bible are translated "worship." The one used the most often means "to bow down and do homage." Another biblical word for worship means "to kiss toward." Put the two words together, and you will have a good idea of what real worship is. We worship God because He is worthy. In doing so, we bow down and pay homage to Him. That speaks of reverence and respect for God. But we also "kiss toward" Him, which speaks of tenderness and intimacy.
