Worship is an act of religious devotion usually directed towards a deity. The word is derived from the Old English worthscipe, meaning worthiness or worth-ship — to give, at its simplest, worth to something.

Evelyn Underhill (2001) defines worship thus: "The absolute acknowledgment of all that lies beyond us—the glory that fills heaven and earth. It is the response that conscious beings make to their Creator, to the Eternal Reality from which they came forth; to God, however they may think of Him or recognize Him, and whether He be realized through religion, through nature, through history, through science, art, or human life and character." Worship asserts the reality of its object and defines its meaning by reference to it.

An act of worship may be performed individually, in an informal or formal group, or by a designated leader.

In the New Testament various words are used for worship. The word proskuneo "to worship" means to bow down to Gods or kings.

Catholicism, Anglicanism, Oriental Orthodoxy, and Eastern Orthodoxy make a technical distinction between adoration or latria (Latin adoratio, Greek latreia, [λατρεια]), which is due to God alone, and veneration or dulia (Latin veneratio, Greek douleia [δουλεια]), which may be lawfully offered to the saints. The external acts of veneration resemble those of worship, but differ in their object and intent. Protestant Christians, who reject the veneration of saints, question whether such a distinction is always maintained in actual devotional practice, especially at the level of folk religion.

Darrell Wayne Evans (born May 26, 1947) is a former third baseman and first baseman in Major League Baseball who played from 1969 to 1989 with the Atlanta Braves (1969–76, 1989), San Francisco Giants (1976–83) and Detroit Tigers (1984–88). He is also the former manager and director of player personnel for the Victoria Seals of the Golden Baseball League. Overshadowed in his prime by fellow National League third baseman Mike Schmidt, he has been described by author Bill James as "the most underrated player in baseball history, absolutely number one on the list," primarily because his defensive skill, home run power, and ability to draw walks in a long career were offset by a low career batting average of .248. He remains one of the few players to have hit over four hundred home runs without being seriously considered for induction into the Baseball Hall Of Fame.

Evans became the first player to hit 40 home runs in both leagues, and at 38 became the oldest player ever to lead the American League in home runs. Evans hit over 20 home runs in 10 different seasons and drew over 100 walks 5 times, with a career high 126 in 1974. In 1988 he hit his 400th home run, becoming the 22nd player to reach that milestone. He retired after having joined Reggie Jackson in becoming only the second player to hit 100 home runs with three different teams, and ranking in 11th place among all-time walks leaders. Evans hit 60 home runs in his 40s, at the time a major league record. He later served as a coach with the New York Yankees in 1990.
