I came across this blog post and question last week: “What’s the message of the Bible in one sentence?”
And it got me to wondering: how would I articulate the theme of the Bible so briefly? I came up with two answers, kind of like the Westminster Confession — one shorter and one longer. Here they are:
The shorter:
The Bible is written to reveal the glory of God.
The longer:
Three major themes of the Bible — creation (man and all things are made for God’s glory), fall (man rejected God’s glory), and redemption (God graciously makes provision for man to be restored to enjoy His glory) — combine to reveal the one great theme of Scripture, the glory of God.
How would you answer that question?
[Aside: He also previously asked the question, “What’s the Key to Healthy Christian Growth in Godliness?” Another good question which merits a concise, as well as more extensive, answer.]
Words of Grace 
My answer to the question is, “God can do it but we can’t”
I like that. Good question to make you think globally and simply, isn’t it?
