We worship God because He's awesome! We worship in order to reflect, revere, and rejoice about God's awesomeness!
True worship can be individual or corporate but must always be grounded in our proper attitude about God's holiness and truth (John 4:24). We can worship God through prayer, songs, and fellowship with other Christians.
Our professed and personal relationship with God should cause us to worship Him constantly, without being "primed" or "pumped up" whenever someone says it's "praise and worship time." God honors genuine worship whether we're at church, in our cars, at the grocery store, on our jobs, or on vacation.
