The first answer to the first question in the Westminster Shorter Catechism, a historical document that is theologically timeless, states: "The chief end of man is to glorify God and to enjoy Him forever."  But what does that mean?  How does one attain to this commonly repeated Christian summation of life, "glorify God"?

First, we would do well to look at the second answer to the second question in the Catechism to find the answer: "The Scriptures contained in the Old and New Testaments is the only rule to direct us how we may glorify and enjoy Him."  This helps us get closer to answering the question.  We know that we must find the answer to how we may glorify God in God Himself.
