Worship means literally to prostrate one's self in token of reverence.
Hence, in many places throughout the Bible people are said to fall down and worship. Worship, then, is reverence, homage. This worship may be expressed in various ways, as singing songs directed to God or by prayer. The manner of worshiping God has, of course, varied during the different dispensations. Burning incense or offering sacrifices, commanded under the law of Moses, is not to be practiced under Christ.
